I personally havent run into this issue on my own models, but iv seen 2 cases of it happen where a model's OSC physics animations that work fine in older versions suddenly are tilting to the back left, i believe this might be an issue with like, value interpolation? These issues only occur after a model has been affected by the editor.
here's an image of the issue occuring on a friends model.

well i figured out a fix for this on the model side, you have to go through each and every OSC animation and set their max value to 255, i think CPM tries to set the value of a value animation to whatever its given through OSC and can get confused when a animations max is 100 and it gets a value of 127
