I had a strange crash, i was playing D'tesh when i toggle gird game crush, and something about turn 430 i was settling new city on new containent (map terra) with a settler on the desert and game crashed.
Solution for first was start new game and when i started gird toggle button was highlighted but there was no gird on the map, so i un highlight the button and load a save, it halpes.
Solution for second was enter world buildier and setup new city with the buildier, and in game delete settler (so i was not cheating

).
And for some changes i've made, is that the wasteland get the same bonus of one hammer and coin as desert for D'Tesh becouse i started seven times on prince level and i was not having any chances for survival, becouse of economy, i had something abaut 15 units and cities somthing abaout 4 pop each at 200 turn and i've must slow my resarch by 50% to sustain army, its hard in the beginig to has large cities becouse oponent dont have large armies on witch you can gain slaves, and first units are wery weak, dont mention the infernal's (deamons) that are immune to death dmg so no chances in mid game with them, only elementals was saving me from them and bunch of werwolves (i get werwolf when i find bestial pelt). Maby some changes in that manner?

its just a sugestion.
