I was playing the Vasari in a small random game. The AI was the TEC. 1 vs 1.
I built broadcast stations, and as soon as one the AI astroid planet was about to flip
due to culture take over, the game crashed froze up.
There was a message on the screen in a box said a certain text string could not be found (basically stating that the enemy planet flipped due to culture take over).
'IDS_PLANETDETAILSINFOCARD_CULTURETAKEOVERSTATUS_ALMOSTACQUIRED'. NOTE: Any following StringID failures will be supressed.
