Hello!

Disclaimer: do this at your own risk.

I ran into a problem that stopped me from quick saving. When I tried to do it, I got a message (see the enclosed attachment) and the game crashed. If you go where your saves are located and nuke everything but your last save, you'll be able to quick save again.

This is a temporary fix until Larian gets around to ironing this out. I reported the crash info, and if you have this problem it's a good idea for you to report it too.

Managed to get this fixed. Turns out it has nothing to do with Larian or their games. You need to get your anti-virus to disable ransomware protection for the save folder.
