Hello world, my first post here, awesome game so far

I also got similar crash and also had my latest save crash every time on loading.
I got it fixed: I went in my documents directory > Larian Studios > Divinity Original Sin > Savegames > affected save game ( in my case QuickSave_3) and deleted all the files inside (it could work if you delete Cyseal.lsb only)
After that the game loaded without crash, a message appeared that it could not load something, but the game worked fine. The only bad thing I noticed is that I lost my revealed map.
