In the early 1500s, with my current game as Silesia. I went Protestant and fought a few wars to expand the religion (and my territory, lol). So, when the peasant's War in the HRR started, i as always got an unrest advisor and stabed up to 2 stability. As Eu4 sometimes gives me luck (so I thought) Austria was weak a got attacked by France, Otto bros and Muscovy (Riga was in the HRR). So I prepared me for war and attacked. After one month or so, I got an alert that the peasants war disaster is looming. When it fired, i stabed up again and unalived the rebels. Turns out with low manpower this disaster has no cooldown. After solving it again (and loosing manpower because of shit troops) it popped up again. Now I'm sitting at -3 stability and 15 unrest, but no rebels and I won the Austrian war. That whole thing is kinda counterintuitive, that’s why we love this game.
