For Rosethundra see if Regina is saying thanks message if yes. Type cheat code 'zapped' while at base. Go to apartment again and wait until Regina and Mason moves to his apartment. Talk to her and you should be able to get that lamp. I need to make a few changes to this quest. First being, no interaction with the lamp when thundergirls are in the map and you captured her. Second one, in case player leave the map after helping Regina without talking to her, the lamp should be obtainable next time you come to the apartment so there's no need to wait for next thundergirl hunt.
Money cheat is working well for me.
