Have you noticed in the latest batch of levels of season 4 that Hanna fiends’ effect remains until the end of your turn even if her fiends are replaced by your own minions?
Unfortunately I can’t add a video to this ticket so below are 2 screen shots (before and after):
I’m guessing the coding is based on it checking at the beginning of your turn if there is a golden idol and then assessing the debuff. The debuff persists until you start a turn without a golden idol fiend. Someone else can offer more, but if they coded it that way, it’s probably working as intended despite the semantics.
