When I apply a wardrobe skin to an item (in my case, I put a new skin on my shoes), the mini is unchecked, and the mini choice is reset to empty. You have to re-select what mini you want, and then check it on.
Very minor. Interesting, but minor.

Not minor for me. I’m never satisfied with my colors, so I’m always messing with my dyes. I’ve already mentioned this bug in numerous threads hoping they see at least one of them and get to work on it when they come back to the office Monday morning.

Set a man on fire, and he’ll be warm the rest of his life.
