Memory leak?

Hi,

Not sure if this has been mentioned, though I looked around and didn't find any mention of it aside from some general ctd problems.  Since the beta patch (and I realize it's still beta, so perhaps this will not be a problem in the final) I've been having lots of ctd's.  Mainly when I try to load a saved game after playing for awhile, sometimes simply when advancing a turn after I get 3-4 cities or bigger.  My memory usage gets upwards of 1gig and the game crashes.

Is anyone else having this problem?

I have to say though, these changes are great overall. Big step in the right direction, thanks for your hard work!

Thanks.

PS - another small thing I noticed.  There are still rings available in game from notable locations that offer the wearer '1 essence point'.  These have the effect of allowing the wearer to cast spells when equipped.  I think this is a great item, but should be very rare... and I get the feeling that this wasn't intentional... that they are in fact left over from earlier versions of the game??
