Pig monsters don't appear in-game

[Artsy]

Ok, so I've been trying to get the pig monsters (all three) to work for more than a month or so and I can't figure it out.
Basically what happens is - they appear in the editors just fine, but when I go in-game they disappear. I have path nodes set up correctly, .msh and .anm files removed from the very start of transferring the AMFP stuff to TDD. I also resaved the monsters in the model editor afterwards. They show up in other CS/mods that have those monsters, but I can't get it to work in my mod.
Others also tried giving me the pig monster files including fixed versions of them but they still don't show up.

wat do.
