Though Larian must be delighted with the reception to Baldur's Gate 3 so far, they maybe weren't prepared for quite how much people were going to play it. Turns out, if you made too many "choices" and "actions", your "personal story database" could grow so large it broke the save system, and the developer's had to release a hotfix to nip the problem in the bud.
