I think the Mask of Magnaminty I JUST BOUGHT has mold in it.
It smells fine but when I opened it and scooped some out, I noticed it has a bunch of little brown specks in it. They're not evenly distributed and seem to be growing where there was some air trapped.
I only think it's mold and not part of the mask because I remember putting on some Magnaminty after it had expired and finding similar crap.
ETA: Lush wrote me back pretty quickly, saying they'll replace the mask and to give her the batch number, I'm guessing so they can take it off the shelves or whatever.
