While playing a game as the Russia then Soviet Union, I experienced a rather highly, highly annoying problem, one I think might have been a glitch.
The Creation of the Red Army event popped up one day, and since I was too busy fighting the Whites, I without a doubt didn't pick the no option, so I lost some units instead of ending up at war with most of Central Europe. Every so often, it seemed to vary from once a month to once every two or three months to once a month, it'd pop up again, and again, and again, and again. I had to be constantly building units to keep from losing all of my military. And even after i beat the tar out of the Whites, it still popped up!
Is it supposed to do that? because that seems...well that seems messed up. Then again, it seems messed up that your options are war with Central europe or lose some units.
