Hello,
I need an answer to this since i have no idea if this is corruption (i hope not!) since i want to continue playing my uberhood + im kinda scared...

So I've added the regular neighbourhoods as subhoods (Strangetown, Veronaville, Riverblossom Hills, Desiderata Valley, Belladonna Cove) to Pleasantview as well as the Life + Pet stories recreated subhoods with OFB + Pets respectively. but when i either go to dine out or play a player owned restaurant, when previewing the menu, Sims get squiggly lines. Is this dangerous? I've checked with hoodchecker and nothing came up. I haven't touched the menu or anything either.

Thankyou

No need to worry, those are the harmless squiggles. They just happen sometimes, I get them a lot with garden gates.
