I have a tactical admiral with t5 Omega Reputation, and I have been completing the ground sets to unlock the costume options. I have completed the Mk XI, XII, and Adapted XII M.A.C.O. sets and their corresponding costume unlocks. I've been checking the tailor a few times since I completed the tailor unlocks, and I am missing Style 1 as I can use costume Style 2 and Style 4. Is this a known bug, and if so, will it be fixed anytime soon because it is annoying to unlock something and not receive it.
Did you get the maco XI unlocked to? That one gives you the Style 1. But you shouldnt need it to get all the maco pieces as far as I know. Currently only clothing piece not unlocking is the Honour guard set Be'Ves. Anyway. Try looking if you have a full set of MKXI. If not, Then its bugged yes
