When using spell Tireless march on a horsed hero (with an army of more horsemen) its movements points increase to 5. I use a movement point, and another horsemen joins the army. Then, the movement points of the final army change, and states a different number. The same, if I split a horsemen from the army, it says it has 3/5 movement points instead of 3/4.

If I give the boots of movement (+1 MP) to the horsed hero with tireless march, it has 6 movement points. But when joining or splitting armies from it, the movement points make weird things (like saying I have 6/7, or things like that). The moves are correct, but the info shown is wrong. It has little importance, but it should be taken into account.

Has anyone seen these issues with the movement points in armies with tireless march and/or boots of movement?
