Annoying bug: commander after morph no longer belongs to a numbered group

This is because morphing removes the level 0 commander and instantly adds a new commander with level 1 after the finished morph(same happens with all of the morphing levels). I remember doing rushes in 1 vs 1 with commander only and when i morphed commander i instantly died after, thus losing the game. So that seemed to be a problem a long time ago and I dont know if has been fixed.

A new unit created always needs to put the ctr+1 again as shortcut.
