share orders allows many vehicles to share order set.

clicking on third vehicle to share order set. Second vehicle has copy of orders but is not shared. Shared order list only shows first and third vehicle. You get warnings about duplicate orders on vehicle #2 constantly.
On my game these are actually trains, #9,10 and 11.
Order set is a round robin of three passenger stations.
Create order set on train #9.
click and share order set with Train #10.
click and share orders with train #11.
Train #11 now shows 'end of shared orders" in list. Train #10 has reverted to a plain order set, not the shared set.
