Game exits when my team is about to enter the home base. Usually, I should obtain information about new technologies to research or items automatically sold, but nothing like this happens. Also loading the game right before entering the home base doesn't help (so it is something stored in the save file).
This is LOAD GAME info (contains one assertion fail):
