Not sure if I might miss read the textbox but a Sim wanted to give me the number for someone named ursula or something... I said yes cause I thought it might be a townie but after I clicked yes I didn't got any new number... And then I checked SimPE and sorted it by names... No one named Ursula exists .-. not even someone whos first name starts with "u"... I used now hoodchecker who might could fix that idk... can the game even get random names of sims who doesnt exist? Or did I miss read or missunderstood the text?

That sounds like it could easily happen in the towns shipped with the game like it did with my test in Pleasantview when I first got my TS2 collection completed more than ten years ago.It happend in my test of Pleasantview just as I was notcing other strange things happening that were the early stages of it getting corrupted.It sounds like a sign of possible early stage town corruption just happened in your game.

I play in a costum hood

It sounds like it might also be possible that a glitch occured or that you're not using any corruption blocking Mods like I do.It's also possible the sim died just as yours got given the number or that your virus software got into files it shouldn't be touching.I had a far worse issue earlier this year with Norton which had fully broken my TS2 install and had to get it repaired.

I have all needed no corruption mods and use hoodchecker... I just have windows defender which never cause me uses personally... Though I'm wondering where the name comes from if such sim never existed or my memory is broken XD

Maybe it's a pet?

That giving a phone numget of a sim can on rare occasions glitch out and fail to complete which happened to me once or twice on my old computer.I was loading from disks back then instead of loading UC like I've done ever since installing UC on this computer.

Didn't you just have this issue? https://modthesims.info/showthread.php?t=671531

Could be some problems left over from that, if any files didn't transfer back to the correct folder. Unknown sims, sims with different names (even different genders, ages or showing up as different species), and similar issues would be examples of issues you could potentially stumble upon when files have been somewhat messed up, or have gone missing in the Neighborhood folders.

Neither the old save nor the current one has such sim... SimPE also doesn't show anyone starting u... also not a pet or anything else...
