Elf quest :Honor
mid siege the game froze on me. i restarted the game and fortunately it doesn't look like i lost anything but time. when the game came back up i was on the world map at the quest starting point just before defending the castle from the siege as the quest asks. i did not try the quest again because losing 10-15 of play time gave me a bad taste in my mouth haha.
what exactly happened was during the siege, i was moving the screen around to see all the units and tried to select a few by holding down the mouse and dragging, at that point the game froze and immediately brought up the dof has crashed message window.
hopefully the logs will help you fix whatever it was that happened.
