Outdated Save crashes when I open the ideas screen

Any ideas of how I can fix it?

Any ideas of how I can fix it?

If it's due to having picked ideas in idea groups that have been changed, there might not be a lot you can do. Maybe see if you can edit the savefile and change the ideas to the updated one. I'd recommend just rolling back to the previous patch and complete your campaign on that before updating.

Which idea groups got changed?

Maritime, Espionage and Naval according to the changelog, as well as some Native National Ideas, Portugal's and Rome's.

Did you pick Aristocratic as a Feudal Theocracy? They no longer can use it, that might be the culprit. I doubt it has anything to do with national ideas, it's probably and incompatible idea group pick.

I doubt this, actually. It'd be really strange, because government changes don't replace idea groups locked to a previous government. Hordes keep Horde Ideas if they picked them, even if they change to a Monarchy, and can to my knowledge even stack them with Aristocratic if they like. I don't see why that should be different if Aristocratic was picked, but now Divine is offered - if anything it should just let them pick both, like in regular gameplay.

If two modifiers have been swapped around, though, the game might struggle, because modifier X is listed in the save game, but the idea slot is now occupied by modifier Y.

This is based on experiences I made when modding the game several years back. It might not still be relevant, but it strikes me as the likely culprit. Or it could be some unrelated string of code buried somewhere entirely unrelated in the patch - I had a few of those, too.

None of those should affect me. I play the knights and have divine ideas and exploration ideas.

It might be a general conflict born from the game checking idea groups and crashing when it realizes someone else unrelated to you does something they're not supposed to, then. Either way, as this patch made some changes to ideas, it's very likely that ideas in general from old saves are prone to cause conflict with the new patch. I'd recommend, as I said before, that you complete the campaign on the old patch, following the rollback instructions in the pinned posts.

You can also try verifying the integrity of your game files and see if that helps, but I doubt it will.
