SO I basically had the same issue as rich S about the geeps disappearing when you start the scenario. This was only on my work cpu. My master cpu they worked fine in.
It didnt take long to truobleshoot the issue. So basically its a blueprint error for some reason located in the final update. now I should have just uploaded the geo files for this update and things would have been easier. what I did was installed v2.1e then installed the update after. The update caused the issue. I then took the v2.1E.bin files for all of the locos and re pasted them over top the new ones. the locos show up and run now. I dont know why this happened but nobody told me about it until recently. I cant imagine how many people may have had this issue. everyone? or maybe no one? But I need to repack the whole thing and reup it. i'll get to it tonight.
