My dear Betonov, you should be proud of your peasants, as they have acquired enlightened knowledge from 100 years in the future and the socialist utopia that awaits them
But in all seriousness, it is a game bug and low contentment should have been resolved with an armed rebellion. Fortunately, I bring two pieces of good news. First one is that the official patch will be released shortly, which should fix some of the game's general problems. The second is that I asked at the official forums and found that we should have used another command for getting rid of strikes/riots/revolts. If things do not show any sign of improvement in a couple of turns, we will be forced to use it. If that won't work, I can always supply everyone with tons of gold and jewellery for your poor, poor peasants.
