There is a small bug in Museum.
When exchanging a Senet game(1*Senet board, 5*Black senet pawn, 5* White senet pawn), you only loose the board and 1 white, 1 black pawn, not 5 like it should be.I still have the extra 8 pawns in my items list.
Cant provide screenshots or replicate this bug, because I dont have another Senet board, but it should be an easy task to check if Im right.
