This wasn’t mentioned in any patch notes but 1/3* Storm Yellow and CMag Red now destroy QS (and Invis Woman) locked TU tiles. Huge nerf to already bad characters.
Both have always removed QS tiles.. honestly don’t have a usable IW, so can’t speak to that.
Any power or match that would destroy a locked tile instead unlocks it. This is the expected behavior.
CMag’s red did not, locking a bunch of tiles then using red to clear the regular ones was one of the normal strategies to get blue to go off.
