Countries like QQ or vassals that have to deal with wrong religion provinces end up with a shitton of corruption besides the usual humongous amounts of rebellions. If corruption won´t be brought down to sane levels (~10% of the effect it had in 1.16.0) just like the title says please introduce another AI cheat, let it play without the effect of corruption. Why? Because the combined effects of corruption, LA, interests, inflation, OE and OP rebels (that disregard LA) etc. makes them go broke every single time. Bankruptcy besides making their provinces useless (eventually 100% LA everywhere) etc. means even more unrest so I have to kill even more rebels than pre 1.16; it is wave, after wave of rebels which makes your game tedious as hell to the point of making me do a video to vent which is something I never, ever thought I would do. If you really, really want corruption to stick around and the game to still be enjoyable by “wide” players either tone down corruption, teach the AI to be good at it (nigh-on impossible if I had to guess) or let it cheat.Here is an example of this, an AI country with over 1000 development that can´t even afford an army and ended up broke despite managing to convert all their provinces (due to having religious ideas):Edit: sometimes the AI can´t even afford to use their missionaries right off the bat.
