Besides allowing achievements to not be disabled when modding, changing Archive Invalidation can also allow some mods to function properly. I had this issue earlier when trying to install StarUI Inventory through NexusMods. Switching up the file fixed the issue and made the menus far more usable. No more big boxes.
