The debug.err file says I used just under half the memory available to my system (3Gig).  This seems to be a common problem though.  It would be appropriate for the game to check for CRASH! conditions before city creation and respond with message like, "Number of Cities Limit Reached" if making another city would cause a crash.  The dropbox service says my debug.err file is too large to post.

Spells which consume some mana per season in addition to the
initial cost, such as "Inspiration," should reflect that in their description.

[TYPO] [BUG?} Apparent problem for a custom unit "Baron."  The design function says I
need 4 crystal, 1 metal, 1 horse and 115 labor to create this unit.  My inventory says
I have 7 crystal, 224 metal and two horses.  The "Train" function says I have insufficient
crystal to create this unit even though my inventory says I have excess crystal . . . finally
got to build this unit.  It took 12 crystals; the design function has an apparent typo in resources required.
