Just so you know... those same cabs mentioned above did have errors, red !, but the locomotives themselves are fine. I did a little test, opened each and every loco I own and all cabs worked fine, look great. So, I went back to content manager, filtered for faulty items, and deleted every item listed. When I went back to listing my locos, nothing changed, no errors, all looked good. So, I opened my previous session, had a look around, tested the controls, all still good and work fine. Well, that seems kind of weird, removed all those things and no problems. Only problem now is the Southern Pacific GP40-2. It is like a ghost, can place it in a session, by itself, add separate other train consists, then drive up to couple to it, end up going through it. I will post screen shots to illustrate later. I could not drive that unit, or add a driver.
