If you need help (and your backups don't work), please post your save file here.   PLEASE ALWAYS CHECK FIRST IF YOU CAN REVERT TO A BACKUP. IF THAT DOESN'T FIX YOUR PROBLEM, FEEL FREE TO POST YOUR SAVE HERE. Make sure to check if you're up to date to 12.2 if certain errors are preventing you from continuing. The 12.2 patch can be found here (4th spoiler), and a hotfix for the game breaking strength bug can be found here.
