MFP elevator door problem

[Damascus]

I did manage to replace the original .msh files, but I'm still having this problem. I've even gone so far as to completely delete the entities and files from my custom story and re-making them all from scratch but they are still flying away through the walls.

I eventually had to just release my mod with the bug still in it, which is irritating to no extent, but if anyone can come up with a reasonable solution, please help me out.
