Good review. This set was one of the first "action feature"-heavy sets I got, and I was certainly enamored with it at the time. One thing that bugged me about it even then, though, was that with all the functions and details on the interior, it was hard to play with. Even my then-tiny hands had trouble rescuing the minifigs after they had fallen in the trapdoor. This is probably one reason for the more open floor plans of modern castle sets. And there's a reason that modern action features tend to use more Technic parts: the mechanisms for both the dragon head and trapdoor could be fragile, and hard to repair if they broke. It's a good set, mind you, but it had flaws.

In regards to 30140, it could fit. It isn't a connection, but the plate should sit flush with the "lip" of the wall element. To see what I mean, try the same construction on Part 4444: That one is coded properly, and allows studs to sit underneath its lip without any problems. And while that exact technique hasn't been used in sets with 53452, it is used to illustrate a problem which did occur in a set. In 2008's Troll Warship, part 4510 ran along the front of the bow. I encountered the problem there, and tried to create an example image which didn't use SNOT, which I thought made it more confusing.

Here's a bunch of parts I want: -45575 -2856 -2855 -40249 -40253 -32074 -30397 -4868a -2994 -6578 -45275 -30488c01 -x1192 -41670 -43557 -53456 -47296 -32174 -32506 -38488c01 -476 -47314 -x400c20 -54604 -50858 -47298 -bb204 -53990 -2907 -55767 -bb201 -bb203 -bb192 -bb189 -55704 -40243 -73090b -30283 -2991 -30164 -30163 -4859 -44036 -2625 -x438 -30034 -30542 -30528 -30535 -33089 -30342 -30286 -2513 -4033 -2356 -30119 -86038 -bb283 -x77ac50 -2850 -85489a -85489b -3939 -32133 -6069 -53494 -30645 -40344 -47461 -54178 -47459 -47462 -54175 -41672 -47335 -424 -32551 -194 -x480 -44790 -57910 -78c24 -44351 -44350 -4088 -47715 -33322 -51377 -78c08 -9244 None of these use out of date connections such as old hinges.

Found two more errors. Part 53452 has a boundary error (Here's an image). Also, there's a boundary error on part 30140 (image). The blue bricks in both images should be able to attach.

I wasn't referring to a baseplate... Fact of the matter is that you can't even place one of the crossbars of that track on a 2x4 plate. There are no recessions for any studs to fit into on it.

Just found another egregious error. Part 85976 doesn't can't be placed on top of studs; the render won't allow it, even though the part should technically be able to, like part 85977 or larger tracks like 53400. EDIT: Just found a couple more. For one, cross-axles do not go far enough into part 59900 (I'm sure that's already been reported). The other is part 60752; it can't sink far enough into open studs (like that on the aforementioned part 59900).

Sorry for taking so long in my reply; I hate working with screenshots and have kind of been procrastinating. Anyway, here's what I've got: 1- Yes. 2a- Image. Come to think of it, this could be an error with part 2637 instead. 2b- Image. 2c- Image. Perhaps not technically a boundary error, but an error nonetheless. 2d- Hard to recreate in an image. Suffice it to say that the uppermost boundary on the barrel is too high, and prevents parts from being placed across it. 2e- Image. 2f- Image. 5- Image. It should be able to attach this way, believe it or not. 9- That works, unless you want a perfect 45 degree angle. Then it's a lot harder. 16- Good point. I hadn't even noticed that! 18- Yep, the grooves on the underside have been used (in sets no less!) to attach plates. 20- Good point. However, that made me realize the real error I encountered: 3.2mm bars ought to be able to recess further into part 6140. The open studs on that part go deeper than most, allowing parts like the two I mentioned to be attached to it. 21- Sure thing. I've made an image to demonstrate what I mean. Note the offset. 22- You got it. 24- Yes. It was even done in a set, 8637 Volcano Base. 28- Try inserting a cross-axle into the hole closest to the ball joint. It won't be able to be inserted more than halfway. 29- Head first, seeing as that's the only way to attach it without there being an unrealistic space. If the beard is put on first it does work, but that's not how it is in the sets. 32- It should indeed sink in further. 35- It's used in the alternate model to 8260 Tractor. 36- No, it's not defined even as far as I can tell. I didn't realize that connection was possible either, until the most recent fire station used it to stick a cat in a tree. 39- No. I've made an image to demonstrate what I mean. 41- I was wrong about that one: A set had me connect it in a way which would technically stress the clip. 42- Compare to the part's image on Bricklink. Could just be a molding mark.

Alright, I just joined, and I have a BUNCH of recorded errors. I'll try to get through them all in this post: -Part 4523 lacks its bottom attachment point. -There are boundary errors on parts 41678, 32310, 4588, 57029, 50747, 30238, and 50967. -Part 4185 has a major boundary error: Technic connector pegs cannot be inserted right up against it. -Corrugated pipes (for example, part 71986) do not accept Technic connector pegs. -Part 4150 cannot be centered on a row of studs. -Part 33121 cannot be centered between studs. -Parts 30103, 30091, and 32138 lack a connection point for 3.2mm bar. -Connection point for 3.2mm bar does not go deep enough on Part 4289. -Part 3063 cannot be rotationally offset from itself. -Rubber bands/treads do not work: Parts 85546, 53992 etc. -Part 6119 cannot rotate properly on Part 30124. -Technic pinhole on Parts 53457, 2695, 44359, 75535, 32126 will not accept system attachment. -Parts 32199, 61356, 30191, 71923, 71986, 57274, 63142, 6211 cannot flex. -Part 45590 cannot flex or stretch. -Part 30396 cannot accept towball attachment. -Parts 54654, 57028, 43750, 40395 cannot be painted multiple colors. -Part 44358 will not accept Part 44359. -Part 30644 will not accept stud connections on lower surface of rotors. -All plates have a boundary error: Technic cross axle cannot recess slightly into tubes on lower surface. -Parts 55296, 55297 cannot be attached to open studs. -Part 44572 has bad render. -Part 4095 does not sink into Part 6143 properly. -Part 47905 does not connect to Technic. -Part 58176 cannot connect to Part 6269. -Part 6587, when connected to Technic by the stud, does not properly sink into the Technic pinhole. -Hinge error in part 44567: When attached to 1x_ bricks with click hinges (parts 30387, 30388, etc.), cannot be hinged more than -46.85 degrees. -Standard clips cannot attach to part 2496. -Boundary error on part 32476: Peghole does not allow cross-axles all the way through; pegs cannot be rotated fully. -On Minifigs, headgear 60747 does not fit over beard 60750. -Boundary error on part 47905: 3.2mm bar cannot sink into underside of piece. -Multiple Minifig neck accessories cannot be attached at the same time; some leave too much space between accessory and head (for example cape 50231). -Boundary error on part 48002: Cross-axles should be able to sink into the base 1/5 module further. -Connection error on part 2714: 3.2mm bars cannot be attached to the peg end. -Boundary error on part 6536: Gear teeth, such as those on part 3647, cannot recess into end with cross-axle hole. -System studs cannot attach to Technic peghole in part 56902. -Stud cavities (such as those of parts 3062, 6251, etc.) cannot attach to top of part 3471. -Teeth of gear 32269 do not mesh with those of gear 6589. -Parts such as 40379 do not fit properly in the side cavities of 59226. -Part 32187 has a connection error: Technic connection pegs can only be inserted from the rear by ½ module. -ANNOYANCE: When a new 2x2 turntable (part 74340) is created, either by selecting it in the brick palette or by cloning an existing part, the piece is dragged by the upper section. This causes the piece to want to connect only to the underside of other parts, while most builders tend to build from the bottom up, meaning the part is more likely to be attached on top of other parts. -Part error on part 30115: Clips (such as on part 30237) should be able to connect to snake at more points. -Minor render error: Part 32198 lacks notches on two sides of the cross-axle hole. -3.2mm bar cannot be inserted into the peg on part 43122. -3.2mm bar cannot be inserted far enough into part 63208; robot arm on said piece cannot rotate. If you have any further questions about any of these errors, by all means ask away.
