[2022] Game crashes on Year 1272

If this campaign has never had any mods used in it, you are all set to report this as a bug! The proper place for it is in the CK3 Bug Reports forum here:

Crusader Kings III - Bug Report

forum.paradoxplaza.com That's where our QA people gather and qualify bugs to send on to the developers.

Attach there the problem save for QA to look into. Then put that campaign aside, and try it as you see new patches come out.

Sorry for that problem!
