Please change the autosave mechanism so that it saves turns in files named after the current season and that it keeps a configurable number of them (like in Civilization IV, for example). As it is now, the PreviousAutoSave does not necessarily contain the autosave of the turn before the last; it is just a renamed version of the previously existing AutoSave file. Sometimes a new AutoSave file is written even when there is no change, that is, an AutoSave file is loaded and the turn is ended without further actions. Therefore, both files contain the same information. And if there was a problem in the AutoSave file (possibly one that did not exist before the game was reloaded), the problem is now in both files...
