Can someone tell me why I keep getting the SBHH message after I've swapped half the Class 450 AI trains on the Hightail to the Harbour scenario for the 455?
I've run the original scenario (before swapping) and ticked DRB in the editor, and I can place the trains manually no problem. And I've run it through RW Tools and it says no problem...? Stumped...
