While progressing with my "perfect building" game, I loaded my last save to discover a bug I've yet to see. It appears cities, roads, and rails have shifted twelve tiles to the right, though the cities are invisible. Familiar corruptions are random forts and pollution squares, concentrated largely in North America, but don't appear until some actions are taken. Civilization crashes in a fantastic array of color when attempting to load hidden cities. Units lie where they should. Most entertaining are the irrigated forests and arctic squares. Surprisingly, the roads and rails are functional where they are; it's not just a display glitch. Moving the Calvary in Africa around, I come across fortified units that don't exist where cities should be; if I move the view while keeping the Calvary stationary, the false fortified units vary. Most interesting is the blank fortified square. I can found new cities, however, but only one since I have 126. Visible and accessible cities are near Alaska and the Philippines, but they move around after some actions. Unfortunately, Terra Form won't load the save; it fails with Run-time error '9': Subscript out of range. http://forums.civfanatics.com/uploads/112588/civil2.7z The game is still playable beyond this point, but cities begin to starve and revolt. Cities become temporarily accessible when construction forces the city view.
