I was assigning a dwarf to a bedroom and it just so happened to be a new mother who had just birthed their first child and the game was paused from that event and notification.

After reloading from a save, but not unpausing, I proceeded with some burrow membership management and the application crashed again.

Attempting to reload this same save and reproduce the crash was unsuccessful but perhaps with these crashlogs you will have some better idea of how to reproduce and track it down.

Incidentally, I also noticed,
- There is also a caravan with wagons on the map which seems to take damage and drop some goods.
- There is an unassignable citizen in the first burrow (presumably dead)
