the MoBends animations are overwriting MTS animations and some are messed-up
Mobends id : "modid": "mobends"

So, I can't fix the MoBends overwriting MTS's animations. MoBends replaces the player model with their own style, so when I go to modify the things I normally do in the model for MTS, it doesn't work because it's a MoBends model. The best I can do is just turn playerTweaks off if that mod is installed.

Fixed in V21.3.0.
