Yes that's correct. It did throw an error message up and I attached the file to my initial post.

I have used the boolprop cheat a couple of times, also aging off/on and I used the kaching one once.

But I've never downloaded anything extra for it

I also haven't used any EPs or SPs. So surely it must be the cheats I've used?

I don't really understand the idea of mods or hacks? I'm so sorry. What kind of things would they be? And how would I split them in half?

The phones I have in the house are just normal ones, bought from the catalogue

I'm not great with technological jargon or anything so bare with me but I think I have a jump bug on my Sims 2 game? I notice it the most when my sim goes to make a phone call, they will either pick the phone up and put it straight back down and jump to their default position (standing straight, arms by sides) or talk for about 2 seconds, and again the phone will suddenly disappear and they will be in default position. The other time I have noticed it is where they are relaxing on the bed and in a flash they will be standing in default position. I have enabled the boolprop cheat to get the error message up. File is attached. If anyone could help me, I would be very grateful
