Does anyone have a solution for this issue? Autosave appears to work but I can't manually save the game. I tried starting a new game and am running into the same issue..
Sorry to hear of your bug @wordaf - My best suggestion is to reach out to the developer directly to see if it's a known bug that they plan on patching. Here is a link to their forum: https://forums.larian.com/
I found that deleting old save data allowed me to create additional saves. I have noticed this same behavior with other games such as CyberPunk. I don't think this is a bug with the game so much as a limitation on the number of saves or storage that is allocated for saved data within the Stadia platform.
