I get corrupted saves sometimes the game will start crashing when changing between cells or when trying to make new saves. This will just happen abruptly and for no apparent reason and can set me back hours of gameplay. Suddenly there's a number of saves that previously worked which are now in an unplayable state. Why is this occurring? I'm using some mods, but not a massive amount. It's hard to track down the problem by enabling and disabling mods because it happens at random, and once the saves are corrupted there's nothing I can do with it.
