Crash occurs when the user adds a sublevel to the current level, edits the sublevel's level blueprint, and then attempts to make a new level.
The state which triggers the crash seems to be when the sublevel is saved, but the main level is not, which results in a prompt to save it on creating the new level.
RESULT
