As stated, when trying to micro multiple forces the control groups will not select upon button press requiring numerous represses making any form of fast juggling of units impossible with groups. Myself and another player reported the same problem ingame. Id also like to request a shift add function to control groups, having to regroup can be a bit of a pain asof.
Hey, have you tried this with all mods disabled? Easy way to test is to add the switch "--nomods" in the command line options in steam...
