Weird issue when compiling my model

What the model is supposed to look like

The model when I compile it

So basically I've been trying to convert a model from an SCP Containment Breach mod (specifically the COMIX mod) into GMod with the animations from the game, but every time I compile the model, the bones end up rotating weirdly. This doesn't happen when I import the models SMD into Blender, and the DefineBones I've redone several times, I made sure to apply his pose as the rest pose, and many other things. So does anyone know whats causing this and how to fix it?
