I lost like 3 hours work before I noticed the game save was bugged. Stopped auto saving and the load/save menu would only allow me to load a game and not save. Quicksave would not work as well.

I haven't seen any mention of this bug before. I had to load a save game and then it started auto saving again and allowing me to save manually.

I am using Gog version with unofficial patch and Gameplay overhaul. Using borderless gaming so it doesn't crash when I alt+tab.

Any fix for this? Not sure what would of caused it. I just got my hotel built and power turned off cause I didn't have enough power plants about the time it stopped saving.
