Another thing I have noticed in the new AOE-DE-1 version is with grouping. In both games, highlighting a group of resources (usually fighters) and with the control-key held down plus one of the number keys the game assigns that number to the group of units. The group can then be controlled via use of the assigned number key.
In the old game, the zero number key was not used, but if tried, it would un-assign any previously assigned number. Thus, if a unit got assigned a group-number by mistake, it could be released from the assignment via a use of the zero key.
In the new game, the zero zero key assigns units to group-10.
In the new game, is there a method of releasing a unit from a previously assigned group?
