Undeletable object

So replaced a bsp with a static mesh or different bsp, im not sure, and now when i click on it it only clicks on one side. I can’t delete it or move it, and I don’t want it, I placed it by accident. I can’t find it in the world outliner, and i’ve tried deleting everything in the world outliner, but it’s still there even after i do. This glitch also happened when my friend did it, and the same thing happened. It is in the way of the play field, and we can’t find a way to delete it. Pls help.

Hi, I’ve had this problem in the past exactly the way you’ve described. Simply go to build and select build geometry, after building it will go away. I’ve tested it in 4.18 just to make sure and it works.

Cheers
