My games been increasingly glitchy at the moment so I've had to reset my sim a lot to get things to work (ie my sim randomly decides to use a computer and she won't stop even though I cancel the interaction, she walks over to the other side of the house, sits down, and then cancels :s ). I use a lot of cheats at this point, freerealestate is pretty common as I've been trying to fill the world with sims, move objects is always on and I pretty regularly use the modify in CAS option when I see ugly townies walking the streets
Also just an FYI since I don't think many people know this, if you just type "Money " (like money 500) in the cheat panel it'll change your household money to that amount instantly, much easier than 500 kachings.
