If you try to click a location right after you placed a stone it seems to attempt to place the opponents stone there but this is fixed after a reload. Need to do more testing of this.
I think this may be fixed now, it's a little hard to tell without working in an asynchronous dev environment, but it now checks that it's still the current player's turn before saving the Game model.
