now this happened positively to me but i will say it anyways.
some guys attacks me with 10 armor units and i had 1 unit on my colony, of course i lose my armor and his units head toward his colony.
here's the bug, my one armor is still there and i am not conquered, no he didn't free me, he never conquered me, and no he's not conquered.
Eh, I try to win every once and awhile. Gotta keep up appearances.
