The game was running fine and then simply froze.  I was trying to build some mansions in my already established 2nd city (of 3 total).  I had built 3 mansions I believe and the freeze happened while trying to place the 4th.  I believe I had selected it (had to reselect as it is defaulting to inn after each build) and was moving my mouse/clicking when the freeze occurred.  I could not do anything in the game but the music was still playing normally.  Was able to open task manager and close elemental but was unable to get back to the desktop (background was just black).  The only thing of note I can think of is that a road was being built to this city and was not yet complete.  Also this city was very close to the other city (~6-8 squares from starting build locations).  Only about 3-4 squares separated them after building other buildings.

The debug.err report is included.  Guessing this is the problem area though there are messages below it.
