FYI - 2* Thor doesn’t disarm traps with color change ability BUT the trap doesn’t go off with a doom purple detonation. Sorry I didn’t get the detonation image but it ended the match when I used it. Have shot of non-disarm with color change and the Yellow one remained after detonation.
If I may pile on, I had the AI use a 2* Chemical Reaction Team-Up which overwrote my Demolition trap. It changed the tile colour from blue to green and overwrote the trap too, which shouldn’t have happened normally (no special tile was placed over the trap).
This is correct and not a bug. Traps are only destroyed when directly hit by board-smashing skills like Lightning Strike, X-Force, Surgical Strike, Unstoppable Crash, etc. (the ones that remove tiles, not simply change their colour or swap them, like Illusions, Deceptive Tactics, Anger, etc.) and by enemy special tiles overwriting traps.
