Re: XML Injector Isn't Working

OneDrive is known to mess with Sims 4 mods and other Sims 4 files, so it's highly recommended not to sync. I'm not sure why no mods would be seeing XML Injector for you if it's both files of the current version, in Electronic Arts > The Sims 4 > Mods or one folder down, script mods are turned on in Options, and you deleted localthumbcache, other than that perhaps OneDrive is undoing changes made to your options file or some other file. I'm currently using it with no issues (I was just testing a mod that relies on it earlier today). After turning syncing off, try deleting localthumbcache so it recreates itself and check options in-game again.
