If your stats are disappearing after restarting your game, install this mod: https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2178619939

Sourcerous Sundries (the gift bag) is loaded after Interesting Uniques, and resets the stats on unique items to their vanilla version. If you want to use Interesting Uniques, make sure you don't enable Sourcerous Sundries or if you have enabled it, add the mod above to your load order.
