- Go to map 3SEWER and let the game run for at least a tic.
- Quit the game.
However I've narrowed it down to SmileHeartBeat actor inside of ZSuper/Entities/Smile.txt being the culprit. Even after commenting out all of the code involved and leaving the Init function with nothing in it, it still crashes.

EDIT: If you "remove Smile" in console, the crash doesn't occur since Smile will destroy the thinker.
