Thank you. I'll pull up a game when I get a chance, and see if anything's changed since I downloaded the last update. I've always been able to get the sims to steal to starting around 8 pm sim time or so. If it helps, I can steal chairs and whatnot from the Bistro and I can steal streetlamps and other things outside on most community lots like the Library. I've really only played kleptos in Sunset Valley and... Twinbrook (I think), so when I get a chance I'll make a game in the other cities with kleptos and see if I have the same problem in other towns. If I remember correctly I couldn't get it to work in Twinbrook either. Haven't really played much in the other cities either, though.
EDIT: Made another klepto in SV, she can now steal inside houses. Still can't steal inside Communtiy lots. Can't steal at the fire station at all.
