I have been involved in a couple of games where, when I receive my turn, I find that none of the units which I gave orders to move by rail or water did so. They all used normal movement.
I have read elsewhere in these forums about not changing orders, postures, etc because that will nullify the movement type order so I double check that to make sure the units still have their rail or water orders.
Is this a bug for some pbem games? In other games I have been in the movement is fine so I have no clue.
