Have been playing Baktria. 257 BC captured Hekarompylos and put it to the sword (as you do after a bad day at the office). Checked what needed repairing and found 6 Satrapeia Stratiotike Klerouchike. This did not look right so I saved the game. Decided on destroying 5 of these building and tried to repair one. Pressed end of turn button and CTD! Reloaded, destroyed all 6 buildings and built new government building and the game was fine. Hope this helps. Fantastic game. This is the game The Creative Assembly should have designed.
