I thought I should report this, even though I'm not entirely sure it's a real problem.
Three times in the last two weeks, a nation of mine has gotten an extra issue on an update. Twice, I got an extra issue for the nation Revolving Door. The first time, I shrugged it off, thinking I'd forgotten to look at it after the previous update. The second time it occurred, I thought maybe it was a problem with that specific nation, though it has not changed regions in a very long time, and I understand that's the usual cause of issue irregularities. This afternoon, I got an extra issue for a different nation (Rank and Vile), and I'm reasonably sure that this time it was not a case of having missed an update. As with Revolving Door, it has not been doing any region-changing lately.
Unfortunately, I don't recall exactly when the first instance of the problem was, though I believe it was last week.
It's not really a problem - I don't mind an extra issue occasionally - but it might be a symptom of a more general problem.
