I’ve spent hours on end messing with scaling in the past. Coming back to an old project after a while, I came into the same issue with my animations. This was by far the quickest and simplest solution and fixed all the issues I was encountering. Ultimately, it all seems to boil down to naming conventions for some strange reason, which is funny because naming things seems to be the one thing designers never do (speaking from experience LOL).
Needless to say, I’ll be renaming my armature from here on out lol.
