Naka's illusion costume (Sleepy Kitty) is bugged when you change it into the illusion room. When selected, the game shows the Maid outfit instead
Oh, that shouldn't even be there since the sleepy kitty arrives in v0.7 that should be out around March 14-16th. I'll clear it out from v0.6 once I'll get some free time.
Fixed in the hot-fixed version. Please update the game.
