I did, actually, exact same story as Atom_Bunny. I did backup all my games folders before doing so, and restored the backups after un-installing, but it obviously didn't do any good.

I like lurking, but this is really starting to piss me off.

Firstly, my sims appearances started messing up a little - all my sims hair turned black, and the skin of their faces wasn't matching the rest of the body. I directed them to a mirror to fix the problem, which crashed the game - I got a 'The application has crashed. The application will now terminate."

Tried removing all the downloads, then renaming my user files, but the problem's still occuring whenever a sim tries to change appearance, even out of my custom neighbourhood and in brand new ones. The game also crashes on trying to create a sim in CAS, and Bodyshop is screwed too.

I really don't want to re-install, as I don't own half the expansions any more, so I'd appreciate any suggestions.

Lately, whenever I've placed roofs on houses they're extremely low, regardless of how wide or long I make them, and well, it's now impossible to build attics (and it looks stupid).
It's been a little while since I've done any building, but I'm pretty sure it wasn't always like this. If I'm not just imagining things, can anyone suggest what might have changed it?

I'm sure none of the other sims met them. I created them, exited the game and did the sims surgery, then loaded the game back up again and deleted them, so I didn't play any families while they were there, and they never left the families bin.

Thanks Lythdan, I'll do that. I haven't had any toddler weirdness though, thankfully.

I have lots of backups, so it's fairly easy to just set back to last time I played each time it happens, I just wish I knew what was causing it. I haven't done any of the things BlastDawn mentioned,  except for deleting a family I used for sim surgery on NCPs, but none of my other sims had any memories of them. Could that still have messed it up? :\

I've tried removing Downloads and Saved Sims folders to check, but the problem occurs rather randomly, so I'm still not sure if that's the cause.

Also, I've been having trouble with my sims want slots for a while... Lots of blanks, although they did fix themselves after a few days. Would that be related to the character file corruption at all?

I don't really want to try re-installing, since last time it didn't fix the problem and it's a hassle on my computer. If all else fails, maybe.

Thanks for the advice, but I tried deleting the caches already. It didn't seem to help at all.

Ah. Thanks for the explaination of the redness, I hadn't been able to find it out from anywhere. Any idea what causes it? I really don't mess about with SimPE or cheats that much... Only for changing sim names or recolouring stuff.

I've been lurking about here for a while, and I used Jordi's tutorial to create this hood, so I thought I'd got it sorted xD I'll blame Pets - everything was running smoothing until then.

Thanks for the advice, anyway. I'll look about and see if I can find out which stupid thing I did.

I had a problem with a lot crashing the game... Tried taking out downloads, which made no difference,  moving the family out into a new house, which also crashed, and then restored last week's backup. It worked fine for a little while, then the same thing happened to a different lot.

Looking at the family in the lot with SimPE while backing the game up, half of them had red thumbnails... I'm assuming that's bad, although I can't see any info as to what's up with them.

I haven't done anything differently recently, added any new hacks or whatever. This happened to my last neighbourhood (after I installed OFB, and this just after I installed Pets) as well, so I think I'll have to trash it like I did that one. So, any help as to how not to mess up future neighbourhoods or even fix this one, would be appreciated
