Update: The problem is still there and @Deniice recently posted the exact same issue just with a flower shop. It seems that the bug hits businesses that offer self-crafted items for sale (bakery/coffee/flowers). I don’t know if the clothing store or hairdresser have similar issues. Here is a link to her post Serious issues with the business system..
@Seiden Maybe it helps if we merge the topics? Since the issue is pretty much the same but with a different business. This really needs to get some attention, because it destroys the whole business gameplay
