okay i sent a bug report with an attached fsm template.
the fsm does NOT become "disabled." it just glitches out and can't be seen or manipulated.
recently what happened is, it went nuts and swapped the fsm view to a different fsm on my recent fsm list. switching back to the affected fsm caused the glitch again, because that state was still being viewed in that fsm. so after it swaps to a different fsm, I have to move the view tab OFF of the STATE view tab, then go back, when it works fine. It's only when I try to look inside the weird states, that it happens - even if I move TO that fsm while that state is selected and its actions 'would' be viewed.
