Since playing the latest Trunk i have had 2 CTD's after playing 2 games. Looking through the Log all seems fine but i noticed this line:
[exception]: ***** Exception during [update:entity[<PlayerEntity 0x8a691b8>{"Cobra Mark III"}]] in [Universe update:] : NSRangeException : Range location + length too great *****
Unfortunately, the player’s update stage covers about half the game logic, so that report isn’t as helpful as it should be. I’ve added more detailed reporting in r3330; it would be very helpful if you threw all those addons back in and see if you can recreate it in the next nightly.
