I also noticed that, while hosting in VR, if you reset the game while tiles are in hands, those tiles will continuously be sent back to the players' hands after they are moved to the center of the table, so they don't fall into the 'bag'. If this happens, you can box select them with the right timing and manually drop them in. As a workaround, I suggest having all players put their tiles on the table before resetting.

Actually the tiles going back to hands thing only happend to me in a single player game. I tested it in a multiplayer game and it didn't happen.
