http://pa.lennardf1989.com/Tracker/index.php?do=details&task_id=2541 here's one http://pa.lennardf1989.com/Tracker/index.php?do=details&task_id=2542 and this most bothersome is the fact a great number of units can't target a bunch of other units namely a commander can't target another commmander. If you have difficulty making him do it but succeed in the end that also counts as part of the bug but basically auto-target is the best way to get what you want and in many case senarios auto-target will fail to function and coms can walk right past each other without issuing a shot.
and no unit can target a commander appart form when they are no longer on starting planet. (don't ask, it's a bug, we're not asking bugs to be logical)
