My process won’t save in Cookcraft

Hi my name is Eli and my gamer tag is IXshankzillaXV I’m having a problem with Mineville game mode  Cookcraft every time I change the floor in my restaurant it doesn’t work and when I place furniture in my restaurant I go to the market and when I go back it doesn’t save even if I leave the game it doesn’t save my property but the restaurant still does save but not the furniture so please fix this bug so I can place the furniture. Thank you
