Now I may live in New Zealand but I do know that if I load the traveling Post office timetable, set at "Clear Summer" and the time is 21.35.. well in Manchester etc it will still be daylight.... What is the purpose of starting the run in darkness when it should be daylight??????
There are a number of fairly big issues with the lighting in the game which, to be fair to DTG, appear to almost entirely UE4 related. Until such time as they’re able to update the engine to a newer version it appears that we’re stuck with these problems. Apparently something they aspire to doing, it’s a bigger and forever growing task to do the upgrade.
I don't think it's an engine thing, it's just DTG has set hard coded dates for the three seasons. Time of day changes a bit everyday, so the sunset times for a day in the beginning of summer would be different than at the very end. Unfortunately this isn't reflected at all in the game since we can't select the specific date on the calendar.
