Unity. Importing new action's corrupt scene.


Like in topic. I import blend files instead of FBX. When importing updated blend with new actions, Unity somehow swap actions.
For example “LegUp.R” after importing (overwritten blend) makes it for example “ArmRot.L”.

And this corrupt whole project.
Anyone have this problem before? Any solution for it. I don’t really know if this is Blender or Unity based.
Also new actions aren’t visible after saving new blend. I must erase blend and load it again.

Hope someone help Me with this.
