I thought that bug was related to cross-saves, not cloud saves?

EDIT: It might have been related to both, based on the reddit bug thread. But this note was in the first Hotfix list:

Disabled Larian Account cross-saves temporarily to solve an issue blocking loads and saves. Steam cross-saves are unaffected.

From my personal experience – I never had an issue with saves, and I never disabled cloud saves. HOWEVER, my Steam cloud sync hasn’t been working. The game works fine and I have no issues with saving in the game, but my saves fail when Steam tries to sync it to the cloud.

I have been using the cloud save.
