There are two factories northern of the map, one is linked to F16 the other is linked to F11. I bombed the factory N of F16 (as F16 was a red field i thought it was a red factory...) But while the acks fires as if they were red, the building counts as gold (and i got TK status for destroying friendly buildings). On the other hand, the factories N of F11 (while F11 was gold) got gold acks with red buildings, so i can bomb them without acks firing at me... It´s like if the buildings where swapped...
