Hi,
I just purchased, downloaded, and played today. I used to play command and conquer/red alert. So I tried to group my 4 engineers by selecting four of them and then pressed CTRL+3 to assign it to group 3.
The problem is everytime I just select ONLY one engineer by left clicking one of it, all 4 of them have been selected automatically.
I tried to deselect and select one of them as well, but still got the same result. All 4 of them automatically selected.
