I just redownloaded and it seems to function differently (maybe I was missing something before).

However, the model functions fine for about 30 seconds, then starts bugging out. Wait at least 30 seconds see if it does the same to you, I will post a video to better illustrate if you need it.

Edit:
I just noticed it is playing all scenes of the mdl. Instead of just playing "walk", it plays all 3 sequentally.

The weird thing is, it plays "walk" for about 3 cycles then literally decides to ignore that argument and start playing all animations. Is this some weird trail-related trick?
