I think the main problem might be Generations. I don't remember the game freezing before I installed it :/ Can I safely uninstall Generations and still be able to use my saves?
More bugs showed up - after visiting China I "lost" a boardbreaker and a chest, which I bought in China's general store :/ I love this game but it's starting to be as buggy as Fallout. Everything would be OK if it didn't force me to start a new game!
