Things have improved since the last update and I've added the cargo pack but the HST scenaro 'chasing yellows' completely crashed the game just short of East Midlands Parkway. Previous issues with HST AWS seem to be fixed. MML mastery Eastgate Depot departure only works on the morning departure neither of the other timetable services triggered the mastery. Difficult to tell Red from yellow signals in daylight although this seems to be a TSW4 issue not unique to MML.
I did that scenario this morning on PS5 and it worked perfectly. No crash whatsoever. I was expecting one given feedback I’ve read about it, but I had no problems. I don’t have the cargo pack yet though.
