I thought that that was the case. But it happened again two days ago.
I hadn't been active for two days beforehand, and when I collected my taxes, it was twice the usual amount (normal). Then I proceeded to pay my bills, and I lost twice the normal amount. So I spent my money, and when I went to view my nation, it said I needed to pay my bills. I went to collect taxes, thinking that maybe the server moved to a new time, but I couldn't. When I went to check the bills page, it said that I owed money for the bills. Now I'm in a state of flux seeing that I will never have enough money to pay the bills back.
I know that this isn't a fault of mine, nor is it the fault of anyone else. It's just a bug, but one that I would like fixed soon. Thanks.
