Hello. I'd like to say that this is a very frustrating mod for me. Because I can play it long enough to see that it would be my favorite mod if only it didnt continuously crash. I've attempted to play this 5 times now. Everytime the same thing happens, it works great until modern times, then at some point during modern times, for no reason i can make out, it will crash to the desktop suddenly. If i reload the game it usually crashes to the desktop again, but not always at the same place, it might move a turn or 2 further along then crash to desktop again. Eventually though, it gets to a point where it wont go any further no matter what decisions i make in the game. The crash most frequently happens when a city is building a new building, though it has also happened when a new tech was being learned, and once seemed to be happening during the CPU moves.
I have read the suggestion that it may be a memory problem, but i'm using a new computer, windows 7 64 bit, with 6 GB ram. I turned all the graphic settings to the lowest quality and it had no effect on the crashing. I played on a small map and I'm still crashing in the modern era the same as I did on a large map.
I've attached my latest save file. For me this game will crash to desktop everytime within 4 turns. Seems not to matter what tech i research or what buildings I have my cities building. If it would help I can upload similar saves from my earlier attempts at playing this mod. This save is using 2.9 with no other mods. I had the same problem in 2.81.
