(svn r7385) -Fix: FS#418 Deleting Train in depot with autoreplace failes
This turned out to be due to continue to drag the old vehicle, that autoreplace sold
This could also be triggered if more than one player used the same company
Now deleting a vehicle will remove all depot highlights of that vehicle
