I've experienced crashing throughout my playthrough, but now it appears it's corrupted my save. I am on The Great Hunt, and when trying to enter Lady Ashbury's manor, the game crashes and says to redownload the game.

I've done that twice and now I can't even load the game. It crashes on the loading the game. Not exactly in the mood to throw 15 hours away and restart, since I fear it will happen again. Can anything be done?
