Any way to edit the .2h file...

[Quitti]

When I do my turns, I do stuff, hit end turn, open it again and do the rest of it. Depending a bit on how complex the turn is of course, for the first 20-30 turns I rarely save it while doing, and increasingly after that. Probably usually around three times for the games which are basically about to end sooner than later. So if I make a mistake, I can just copy the 2h out of the savegame folder or quit without saving and continue from where I left last time.
