I haven't been able to repeat this error but I have a couple of notes that may help in tracking it down: The units start out flipped from the beginning of the fabrication process and remain flipped until they are required to act by their AI. (Like needed to fight another player.) When flipped they can't be selected or controlled until they are returned to normal by the above process. (See units in right side of screenshot for example of this.) This base was located right next to the south pole. Aircraft had a similar error, except they returned to normal as soon as they lifted off of the factory's pad. (I would of placed this in an issues thread but couldn't find one that matched.)
Isn't that the whole point of the Alpha Discussion subforum? ;p I'm sure this will get moved over there by a Mod. Mike
