Can't delete something on my land

There's an extra set of walls on my land from the building I've, well, built. For whatever the reason, I cannot delete them! It's not only annoying, but it blocks off half of the first level of my structure.

How do I take care of this?

There are various things you can try. If your land is deeded to a group, set these walls to a different group and enable autoreturn.
Or ask your neighbour to enable autoreturn, and then change the object coordinates to move the walls off your property and onto his land.
Or set the object for sale (the original, not copy or contents) and have someone buy it and pick it up.
Or split off a tiny parcel of land right under the object, make sure it only has those prims on it and return all objects on this parcel.
Finally, if you don't mind wasting prims, you can also lift the thing into the air, by setting a z coordinate of 999. Or drop in a script with the line llSetAlpha(0,ALL_SIDES); in the startup event.

Btw... are you close to the 0,0,0 coordinates of your sim? In that case, the walls are shown but not really there, and you can't manipulate them. There's a bug that causes objects to display a copy of themselves in the 0,0,0 corner.

We had over 100 'ghost prims' that we couldn't do a thing with on our land (mainland Rosieri), whatever we tried they just wouldn't go.

So we opened a live chat and asked for a region restart, which cleared the issue.

Might be worth a try.

There's been some promising movement on this bug in jira:

*points up*

Ghost prims have been occouring. However linden labs is doing maintenance right now so Im hoping this gets delt with.

It got dealt with the other day, I think. I logged in and it was gone.
