Obviously quite upset here. I made a lot of changes to my sim's appearances for her wedding by Editing in CAS. Not all the changes I made in CAS were using Mods. Some were regular edits that came with the original game (non-custom contents). After I clicked the check-mark (the save button), the sim back in the live-game looks exactly the same as before I edited in CAS. I really hope the edited sim who I clicked the check-mark for is saved somewhere and is retrievable?

Restarting the game did not help. Disabling then enabling Mods again did not help. I do not want to Start a New Game or create another sim to replace the existing sim. This issue is not isolated to this one sim and is not isolated to certain Mods. This issue applies to all Mods from various sources and to all non-custom/non-mods contents.
