Sometimes, when clicking the "next turn" button on a late turn, Civilization V freezes (and in the background Windows shows an error, so it actually crashes). When this happens it is reproducible - i.e. if it crashes when trying to go from turn 396 to 397, then when loading again turn 396 or 390 (from the autosave) or even earlier, it will still crash.
Searching online shows this happens to other players as well, typically on late game turns in huge maps - but I was not able to find a solution. Does anyone know of a way to continue playing once this happens?
