The click hinges and the collisions are two separate issues.
As far as the click hinges, I don't own the set, so I can't speak with any certainty on the subject, but just based off the angles in LDD, as well as photos, it appears to me as though the top four wings when folded close to the body cannot get to a full 90 degree hinge angle, as well as the side wings not being able to achieve a 67.5 degree angle. The top four are definitely not posed at 67.5 degrees as well as the side two are not posed at 45 degrees, so logically, they are somewhere in the middle, and thus to my mind, out of click.
Specifically in my LXF, they are at 82.5 and 62.5, so 7.5 and 5 degrees short of a 22.5 multiple. Even if you close them as tight as possible, they still don't get in click. If you compare my angles to any of the published TLG photos or the instruction manual of the set, you'll find they are quite comparable regarding positioning. As well, I took a look at the set at the LEGO Store as mentioned, and they were definitely folded as tight to the body of the vehicle as possible, yet to my eye, none of the hinges were at 90 or 67.5. Obviously without actually holding it and moving the hinges around and feeling them click or not click, I can't be 100% certain.
With regards to the click hinges having slightly loose tolerances and being able to be a degree or two off, just experimenting with some real ones right now, the only way I've found to get a few degrees off and stay in click is through application of force (basically holding it there by hand), which none of these parts in question would experience. And if you do get it to hold at say, 12.25 degrees, the forks start to spread out from stump and I'm guessing this is what is bad for the parts. This happens as well at smaller angles, even 5 degrees, while the ridge of the fork is still technically in click between the fingers of the stump.
As far as the collision issue, it's the columns coming up to the rearmost wings that are colliding with the side of the vehicle. This image gives a better idea of the affected parts:
The blue column was less than a millimeter too close to the green side of the vehicle, which clearly is not an issue with the actual physical parts due to the looser tolerances of Technic beams and pins. And as far as adjusting for the collision, that allowed the entire rack assembly to which the rearmost wings are attached to be slid further backwards as intended, allowing the wings/hinges to get even closer to a proper multiple of 22.5.
Either way, I just thought it was an interesting issue in LDD, especially given its tendency to prevent "illegal" building. Whether it extends to the real set or not, we'll just have to wait until someone curious enough about it checks it out. I still have to catch up on Alien Conquest and Atlantis sets, so it probably won't be me any time soon.

That is truly flagrant. I do
have these pieces on hand and the 61184 pin is definitely kept under compression. Ouch! Funnily enough, LDD allows it without any issues.
