A minor software problem I've noticed is an inability to deselect a selected target hostile unit if I disengage combat to withdraw and go shopping.  To better explain if I am fighting an enemy Rook but must flee, port to base and go to shop, the enemy rook's picture will be in the upper central portion of the screen in a box that cannot be moved or exited.  It can be replaced by targetting another hostile unit but it cannot be disengaged or cleared away to the best of my knowledge unless the unit that is selected is killed. If there is a button that clears the combat que I have yet to find it.  The minor but annoying result of this observation is that the player is unable to purchase low cost items such as healing potions or tier one gear as the target box hovers right over top of these items on screen once you activate a shopping menu.  I think a quick fix to this might be the usual right or left clicking an unoccupied area of the map to clear the que away, and even if there is a button to clear targeted units the option to be able to do it with the mouse would be an easy and convenient alternative.
