Technically

The new saddle was restocked last night 1hr later, gone now

Reindeer is available from the set 10275. Unfortunately for the UK members, I've only seen the blacksmith stuff get restocked at 10:30pm est, sometimes like clockwork (idk how the different regions get restocked). I wager that tonight they restock the shields (they weren't available last night).

Waiting for orange space torso

The Tan Horse and Black Falcon bodies have been restocked at least 5 times in the recent weeks. I just check the website a bunch of times through the day/night looking for patterns, horses are up for about 30-45 mins, torsos are up for 1hr-2hr. It's usually the same time at night, eastern US (look at timestamp of my post in previous page). Now torso/legs/shield/helmet seem to be restocked at different times, so I might suggest getting a few pieces here-and-there if you see them in stock. Lego doesn't need to change price/production/customer limits. People just have to try to get what they want.

Tan horse is gone, and I didn't see the reindeer because the element number crashes my B&P page. I can't bring myself to buy any now.

White Horse and Black Falcon bodies are in stock for US people

Snoozers

Yesterday I saw that the Cyber Drone head is available. Then I saw the white horse was in stock again (and shoulder armor/wagon wheels)! I added one to my cart, few mins later decided I wanted another 1, but a pop-up told me that I've reached my limit. So perhaps they've implemented limits on certain items like some of you have suggested. Probably a good thing!
