Multiple prop_dynamics are changing position during compile

[Panckakebro]

I have a bunch of prop_dynamics to create a roller coaster in the skybox. The tracks are aligned in hammer, but in game they are misaligned. However, they work perfectly fine when they are prop_statics. Why are the prop_dynamic track models changing their position during the compile?
This is how they look in hammer:

This is how they look in game as prop_dynamics (doesn't work):

How they look in game as prop_statics (works):

I think I fixed it by nudging each prop individually so now they are misaligned in hammer, but aligned in game. Sauce engine moment.

Well if the props are in your 3d skybox, keep in mind that the 3d skybox is (by default) 1/16th the size in-game as it is in Hammer. This also means the position of every track relative to every other track is reduced by 1/16. My guess is that this was caused by the tracks not being in the correct position in the first place due to improper skybox construction.

I opened the vmf up with notepad++ and the models have the same exact integer z coordinate. Also the scale for the skybox in this map is 128x. I think its just some weird position clamping thing for dynamic props, since they maintain their position as static props.
