Campaign map movement bug

I found this bug randomly without realizing it a few times before i found out how to replicate it. Take any army a few tiles away from the coast and load it into a boat (must be a fresh turn) so as to use some of their movement points, after they are loaded in you can move the boat, do not click on the unit cards of the fleet, just order them to sail out, once they have reached their farthest point to move, press CTRL+A (to select the entire fleet) and you will be given an extended movement range that you can make them move in (i think this is equal to the movement points they "lost" because of the time it takes the army to reach the boats.

This bug also seems to work with land armies, but I am having some trouble reproducing it, but have had it happen several times after I started using Ctrl+A to make sure i'm moving whole armies.

Apologies if this has been posted before, but i havent seen it mentioned.
