Having encountered no issues previously playing Great Western Express have now had 2 red light bugs on the maidenhead peak time 166s. First one is on approach back to London on the ECS move and the second occurs just before Maidenhead on the 1715 from Paddington both very frustrating
Were these "continuation of services" or freshly started journeys also did you save the game or commenced the game from a save game at all?
