This would be my first time posting about a bug, so bare with me on this.
I have both static, and random npcs enabled.
Had to set up the no auto pick up zones in a house, and at one point wanted to cancel out of a certain zone.
So what I did was press “Shift-Y” then “A” to add the zone, but changed my mind and mashed escape. It got stuck at the name screen so I didn’t think and hit “Enter”, and boom game crashed. 
I am using experimental version 0.C 3286
