As the title suggests, I do not meet the Union Pacific AC4400 from Cane Creek anymore. You can select and drive it, but all other locos in the consist and all AI locos are SD70 and SD40. This was different when SD70 and AC4400 would be mixed. A step backwards. Why you makin' it so hard? PS5, Sherman Hill (obviously) and Cane Creek installed.
Strangely enough, I get to see a lot of the Heritage Collection as well recently. Maybe they adjusted the algorithm or something?
