0.9.11 [Win 10] Firestarter anointment not working

I got the Firestarter anointment (playing as Evoker) but it doesnt seem to be working. Enemies do not start the battle with the burning debuff nor do they get it in later turns.

I also checked if their take burning damage without the debuff icon each round but that also isnt happening. So it seems like for now the anointment does nothing.

edit: seems to be working properly now after a clean install of the game.
