Had a couple of out of memory errors. the debug for last one http://ifile.it/7goxy6k/debug.err i seem to get up to the 500th i think, ehh.. I get to interested so i forgett to wathc the turn counter. 
On CTD, i get one (sometimes two) standard Out of memory error message box, happends "randomly" during the later turns, no other reason than the message.
