Re: I can unlock any door in France, is this right?
@Sunny_Rio No, that's not how things should work. The only reason I've ever seen this happen is if the lot in question is my sim's home lot. Even if you're using cheats, they shouldn't be active on a reload.
If you've reloaded and the issue is still present, and you haven't accidentally moved your sims to the tomb lot in question, it's probably a mod issue. (Some mods can enable cheats as well as adding their own features, so this could be a cheat enabled by a mod as well.) Try pulling all your mods, as a test. You don't need to save your progress; just see whether it helps. If it does, use the 50/50 method to sort through the files. NRaas mods are fine, they wouldn't cause this, so you can exclude those from the test.
