Thanks for the reply. I'm loading it from steam so looks like a roll back isn't an option. I'm wondering if I uninstalled, then reinstalled with GOG if that would work. I'll give it a try.
Update: So GOG doesn't recognize Baldur's gate as an eligible game from steam after linking my steam account to GOG. I'll look into the cloud saved saves and see if that holds true for me as well.
Update 2: Both Cross saves and Cloud saves that successfully uploaded are crashing as well. Experimenting with an old save and saving now. I already created a new profile and new character and all of those saves work. But obviously it started post last patch.
clear one question up, are you using a Gog build or a Steam build of the game?
Steam build = cloud saves are different to cross-saves - the first is controlled by Steam and the cross-save is Larian
Gog = check your Larian account... reading your issue sounds like you mixed up the account Steam and Gog talk to Larian with and yes once you change patches [up or down] that will make all the old saves worthless now
