So I think other people have faced this before, but somehow if you put down an astral spirit before you die or something, the ability gets bugged and when you respawn there's always a return astral spirit ability, but the spirit never returns and some abilities like Storm Spirit's overload are always toggled on the whole time, I played a game like that today. The spirit was abusing it's overload passive by using the bug, so the game becomes unusally hard. This should be fixed fast cause it's almost cheating if someone can figure out a way to use this bug
the spirit does not trigger it. The hero does. It procs upon summoning the spirit (as it should), but it also procs upon casting the return sub-ability (which it should not). The sub-ability has 0 cooldown and can be spammed until the spirit has fully returned.
