Editor Connection Was Lost Error

Randomly came across this one but at least it’s easy to reproduce: https://imgur.com/a/Z8EEify

Repro Steps:

  • Create an empty game.
  • Use the shape tool to make some big block.
  • Switch to the volume select tool and extract the shape.
  • Deselect the extract and reselect the extract.
  • Ctrl+X to cut the extract.
  • Ctrl+Z to bring it back.
  • Ctrl+C to copy the extract.
  • Enjoy the crash.

Edit: I forgot to mention I came across it in a game I was working on so I tested it in a clean slate and it still happened. The name of the test game I created is “Crash Test” in case you want to take a look there.
