2) Can you make units in the build que spawn on a certain hex when they are ready by default? This would add to the historical accuracy of the scenario I am currently making. I looked at the script for spawning units in other campaigns but am not sure if this is workable or something that would be clear to the player, as they need to be able to see where their reinforcements are headed.

3) Does supply continue forever on a rail line? I think I had this issue before, where supply would suddenly end after a certain amount of hexes from a source, despite being far above 1 supply.
That is all.
