I get a rather starnge effect when coupling the Black5 up to a string of BR 12T vans in a free-roam scenario that I've created. The vans were placed by myself in an unbroken consist, but when I back the loco (tender to the vans) up to the vans and hit cntrl+shift+C the vans jump one at a time in a mexican wave style. Quite amusing
What isn't quite so amusing is the fact that the tender decouples from the loco and won't couple up again!
Has anyone else had the tender run away when coupling?
Cheers.
