Several times now, when I've tried to load a saved game when I've already been playing (go to main screen from the game, hit load game), the game crashes. The music stops, comes back, then the screen flashes and that's it.
I have an HP Pavilion 9501f running Vista. The crashing happens on Autosave and manually saved games, but not all the time -- maybe 50%.
AN unrelated problem -- I loaded an Autosave from several turns before I had finished researching a tech. WHen I loaded the game, the tech wait time was down from 3 to 1 day.
