I was in the pits of namtur (the one with all the goodie cave), winter of 237, I was on guard with my sovereign stack waiting on a group of pioneers to be built, hit return and it crashed.  Sent the debug.err to stardock support.  Also, I defeated all the monsters in the waerloga the dragonlord, including old waerloga, but I couldn't claim the resources, it stayed orange, unless it had some monsters under water in the thin strip of water next to the area, which has happened before.
