We were in the process of renaming some custom actions and all of a sudden the playmaker editor lost the ability to display state machines. Also all the playmaker icons and gizmos disappeared from the hierarchy and scene view.
The only thing the playmaker editor displays are two perpendicular intersecting lines (like a + sign) where the state machine minimap used to be, almost as if the state machine view canvas had messed up dimensions or coords.
We've tried everything to fix this issue, fresh new project, reload project from source control, reinstall unity and nothing works. The only thing that fixes the issue is to create a new user in the machine and open the project using this user.
Does playmaker store some of its data somewhere in the machine outside the project? Perhaps something to do with the user? I would hate to have to create a new user every time this problem arises.
