fixed- old thread

If you have NRaas MasterController and MC Cheats in play, click on the ground of the lot and NRaas > MC > Object Stats > Non-Inventory and select to flush everything that has the word "jig" in the name.

Alternatively, or if that doesn't work, retreat to Edit Town, evict everyone to the side of the screen, copy the residential lot down to the bin, bulldoze the original, replace it, and move everyone back in without having left the screen (note that promised wishes and opportunities in progress will be lost that way). Stuck jig objects, which are usually invisible, cannot survive that kind of reset.

Sorry, I saw a bed up there someplace and incorrectly assumed it was a residential lot.

With all of the sims far out of the way (MC Reset the lot if you have to), can you get a DE Radius Purge to accomplish anything on or near those two tiles? Be careful (or be prepared to quit without saving) if the Purge removes more than it should. Like the staircase, although you could put that back, or something more critical.

If that's no good, back on the MC > Object Stats, there is nothing listed that just shouldn't be like more gems or a spawner? Object Info instead of Stats should allow you to focus on certain objects like that if there aren't multiples of the exact same kind all over the lot. And does buydebug reveal anything there?

@Karritz has a tutorial video that you might want to try to fix unroutable areas that exist in a build.

Here's a link to her video which is part of her tutorial playlist. The lot is an EA build as I understand it.

Oh thanks for the video, I will give that a go as well.

The reason I asked is because the message you got about not being able to place a lot on a road reminded me of the very much out of place invisible road segment I found in a world from My Sim Realty. I actually had placed a lot on that spot in CAW, but when I play tested, a taxi drove right onto the lot to pick up my sim. I removed it in CAW by clicking where it was, then when the lines for moving a road segment appeared, I was able to delete it. Did you try starting a new game in that world, then placing a sim in the same house and testing to see if you get the same issue? If it is an out of place road segment, you can't remove it in game. It probably isn't, but you never know. It could also be some other world object that is hidden just below the surface. World objects don't show up in an MC search.

I get it in ever save I was wondering why sims kept getting stuck I finally got annoyed and checked and that's how I discovered that lot

I suggest you try saving the house to the library, bulldozing it from that lot, and placing it on a different lot. If it works there, then there probably is something in that location that shouldn't be there.

Is there a basement under that part of the lot? If there is, check if there is something placed below the problem tiles that could be poking up and preventing the sims from using them. A lot of objects poke up through the floor as they are higher than normal wall height. The Group Science Project, for example, pokes up through 4 levels - the level it's on plus 3 levels above it - this is due to it reserving space for the flame that comes out the top of it.

@Karritz
There is a basement.I'm gonna try your video as well later on.I will check on that as well.Thanks!

Did you watch the video yet and try using CFE cheat to 'dig' down and look around down through the hole. Often things sink below the surface. This makes them invisible on the surface because they are under the ground. I've retrieved all sorts of things this way. These things are not in the basement below. It's a different issue. You need to use the terrain tools to lower the ground level and look around down through the hole. If you find something all you need do it click on whatever it is and then hit the Esc key to make it pop up onto the surface.
