Random polygons on lots

[Cake]

Hello,

My game has had a somewhat persistent glitch where a random polygon will show up on lots. It looks like this:

Lot #1:



Lot #2:





It also happened on another lot, but I don't have pictures of that one.

Initially I thought it might be due to a CC spiral staircase that was on the lot. So, I uninstalled it (and I have very little CC in my game.) For awhile it seemed alright until POOF! It shows up yet again on a lot where there's absolutely no CC.

It's visible in live mode and in build/buy mode. Also, for some reason the game seems to slow down/freeze when I'm playing on these lots. This is more irritating than the fact that it's simply ugly, as I've worked for many hours on some beautiful lots and they suddenly are rendered unusable when this polygon shows up. I first notice the polygons in build/buy mode.

I am playing the base game + Late Night expansion, no mods, a minimal amount of CC objects, and a few EA store objects. My game is patched up to date. Using a PC with Windows 7 on it. My graphics card is an AMD radeon HD 6450.

Thanks in advance.

Do you use the CFE cheat in building? Is there a part of the building under those pieces (as in below the level) or was there an area under there that you may have demolished?  I've had this happen a few times. Have you tried to use the sledgehammer tool on them in build mode?

The sledgehammer worked! Thank you.

In the newest lot I haven't used CFE, but I built the foundation over some ground that I raised in order to create several stairs in front of the entrance. In 2 of the lots that got this glitch, I did some wonky things with the foundation first, but in the other lot I didn't do anything strange with the foundation.

Glad it worked. I've had it happen from time to time and usually it is after doing something 'different' in the area. I've also found that you have to give the lot a good look over from different angles and heights to see them all.
