The issue: Our guild recently got the Restaurant up to Level 12. The next day, investment was down significantly, and the chef was level 11 again. Our guild membership looks unchanged, so its not a case of someone leaving, at least at first glance. A guild member though says that someone joined and immediately left at some point during that day. That doesn't explain the loss of investment, but I mention it in case it is relevant to the potential bug.
So, is there some other way we could have lost investment in the Restaurant, or is there a possible problem?
