Like to preface this by saying i have searched the whole internet to no avail, found several people with this problem (usually several years ago) but never found an answer that helped.
For some reason there is a junk action that can not be deleted.
As you can see, all of my actions are fine and dandy except for Cube.040.action. When I export as FBX into unity, it can often nearly crash Unity because there are all of these junk animations called [Object Name]|Cube.040Action.
This action is not visible in the NLA editor, cannot be cleared in the outliner, cannot be deleted in Data-Blocks and cannot be cleared by python unless I'm missing something.
What leads me to believe it is some kind of bug is occasionally it will appear in the NLA editor, but is not deletable as the expand button does nothing when clicked.
Any help would be appreciated and im willing to upload the blend file if that would be helpful.
