In our little central Europe, we change mission.sqm almost every moment ;D OK, I'm just kidding... But be careful - if you change ANYTHING that has anything to do with the side-changed unit, it's side will be turned back to normal. You cannot:
- change anything in the "edit unit" window in the editor; you cannot even double-click on it and press OK!
- change or add any waypoints for the unit
If you do so, you'll have to edit the mission.sqm again
- I've been messing with this stuff few days until I found out what's going wrong ;D
Still you can group the unit with triggers, markers etc.
