In my past game with amumu, from the beginning of the game to it's end : I didn't need to be hit in order to use tantrum. There was still a cooldown.

I took a screenshot when I noticed the bug and I typed a /note. Eventually I died and I took a screenshot again and wrote a /note. Dying didn't fix this tantrum bug.

Anyway, I'll send you my logs once I find out how to do it on the new client.

yeah tantrum is still bugged, sometimes it works sometimes it doesnt..

oh, that makes sense
