Simple question, my first world map that is very large with many assets always crashes when I hit delete on an object, whether it’s a static mesh, a light, VFX, sound volume, character, foliage, anything. Does anyone know what caused this and if I can fix the issue? This, of course, is urgent. Thank you in advance.
Hey, I appreciate the fast response! I will try this right away! Am I supposed to copy from the world outliner? Thanks!
Could do. What I did, was just click in the viewport and CTRL-A/CTRL-C 
That really worked! You saved my bacon! Thank you very much!
I had this kind of problem. Solution is to open two copies of the editor. Open you bad map in one and basically copy and paste everything into a new map in the other editor.
You can just do a CTRL-A/CTRL-C, not individually.
If it still crashes, you have to start guessing which things not to copy over…
Hoorah!
