I didn´t know that. This could explain, why I never had these crashes as CCM is constructed and tested by me on Monarch level. Moosezilla played in Regent level when getting that crash. On the other side ThERat reported such a crash in demigod level, which means the civ that lost its last city had at least 12 free units for demigod difficulty plus 4-10 free units for the government plus at least one unit (that was too much to support) remaining on the map. Together these numbers are at least 17-23 units. Moosezilla in his crashing Maya game had 10 Mayan units remaining on the map. Now I understand, why the Mayan form of government -Theocracy, which gives 10 free units- couldn´t help in that situation. I don´t think, that to add 23 more free units in the difficulty level for the AI even to Warlord and Regent level, is a good solution. I still wonder, why normal Civ 3 doesn´t have such crashes, as even when the last settler should have been killed after loosing the last city, there wasn´t such a crash.
