100% certain. It was literally -Log on, check attack messages (of which there was two), collect taxes, pay bills. Then I realise I forgot to check my soldier count, so I check my nation, (turns out I wasn't in anarchy YET) deploy max soldiers and tanks, check my nation, I'm in anarchy. No new messages of attacks.
When I deployed, it also seemed that the tanks didnt all deploy, or something funny like that. I didn't mention it because I'm not as sure of them- I pay less attention to tanks since they don't throw me into anarchy.
The only possible thing I think I might've overlooked is the step after I collected taxes and paid bills, maybe I had my nation open in another window, and saw it there, however I don't think so... I'm 85% today that I refreshed the page twice, to be sure.
Also, thanks for the advice Jack. I deployed one less than the max deploy today, and I didnt get an extended period of anarchy time.
