Sometimes, esp. on customized games of BTS, when i get near the end, the menu changes. ie. can't retire. and when it gets to jan.2050 it just keeps going, though previous turn said "1 turn to go". recently won a game by space race, cultural victory and time victory though the spaceship was still flying with 11 turns to go in 2084AD. I launched about 2030Ad. A bit frustrating! Anybody else?
