Hotfix (Save Protection)

This is a small hotfix to address save corruption issues that can happen when moving spell enchantments at an enchantment station. I have also added a save backup and recovery system that can catch potential corrupted saves and restore previous versions automatically (instead of losing your save entirely)

I apologize for anyone who lost a save due to a bug. This patch should reduce the likelihood of that happening in the future.

Thanks to everyone who brought the issue to my attention!
