@Kriegskanzler You can, if you right click on EU4 in steam -> properties -> betas, you can go to previous update and uncheck Origins in the launcher. If you wait maybe 30 mins from this message, there is another patch coming which resolves a lot of crashes too, so try that first.
This hotfix fixes the issues with AE penalties from Personal Unions, a recurring crash issue affecting some people at certain dates, a problem Army Tradition on Development Cost, and a few other issues.
This is the exact same patch that has been available as an opt-in beta patch on Steam since Friday. You should be able to continue save games from both 1.32 and the 126.96.36.199_beta after updating to 1.32.1.
