Can I just check one thing, please, as this will be the first time EVER entering into a challenge! :S
Do I have to move my sims to an empty lot, or move them into a pre-built house. If the former, is there restrictions on the size needed (i.e., must it be a legacy lot?)
Sorry if the answer is listed somewhere. If so, whilst I've tried to find it, apologies for not trying hard enough!
