Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General How do I unpack the .lsv save files so I can edit?

Currently having trouble packing the lsf files back into a saved game file that doesn't crash the game when trying to load it. Every time I try to load, it says the saved file has been tampered with and then crashes. It even does this when I only changed one number in the entire global.lsf file. There must be a validation check somewhere but I see no mention of hashing inn any of the lsf files.
