The unlock should be show, and you just have a few spelling errors in the second one. bb.showhiddenobjects bb.ignoregameplayunlocksentitlement (ignore gameplay unlock sentitlement)
I've unlocked career items and hidden items (and you don't need testingcheats for it). "bb.showhiddenobjects" (hidden objects, also select debug in the filters to find them more easily.) "bb.ignoregameplayunlocksentitlement" (to unlock career items)
When there's noisy neighbors in apartments, aren't we allowed to knock on their door? It wasn't giving me that option so my sim just passed out on the floor.
I've had all those problems except the musician one since I don't have a musician. The lag for switching time speeds and sims waiting to do another task annoys me the most.
You could always turn on testingcheats then type cas.fulleditmode. After that, you hold circle and click x on the sim to get the option to fully edit them and age them down. Save the changes to your library and make a new game (if you want to be able to unlock trophies, otherwise you can just continue your current game).
