SOLVED Mission Replay corrupted my save

[GoshU]

So I replayed a mission, saved my game and when I returned, it crashed whenever I reloaded that save. Is there a way I can revert to a previous save(no, I don't have another recent save)?

So I knew of a way which could potentially work but I was too lazy to do it... Yesterday I decided to back up all my mods and packfiles(because some of them are edited by Sandbox+), I verified the integrity of the files and I managed to run my save with a vanilla game. Then I put all my mods in the directory again and... the save CRASHED AGAIN. Fortunately, the game had autosaved and I managed to run the autosave and then saved afterwards.
