The problem
It’s basically impossible to see what priority an animation has without running some code to load the animation and check/set priority. If you uploaded your animation with wrong priority you can either custom code your script to set the priority (which gets messy) or reupload the whole animation.
My suggestion
Is that animation objects have a Priority setting.
This can be set to:
Idle, Movement, Action, Core or Default.
Default will use the uploaded priority. All animations would use Default as default setting.
Did I upload using wrong priority?
Yes.
Am I asking for a complete system overhaul just to solve my minscule, self created issue?
Also yes.
