I've not heard of this work around, how does it work?
Firstly, yes, it's been disabled/fixed and no longer works whilst the Marauding Boffs still can't be edited - nice priorities there Cryptic.
Secondly, it allowed you to mix and match clothing pieces from everything you owned which is why you might see characters running around in Omega Armor with a MACO helmet (and a plethora of other combinations).
This also allowed KDF players to edit the features of their Marauding Boffs by changing their appearance and allowing players to select clothes from the 'Off-Duty' tab (my Marauder Boffs are wearing the C-Store 'Mercenary' outfit for example).
Sadly, even this less-than-perfect solution is no longer available to us.
How disappointing. I was looking forward to my renegade BOFF. It's a bit deflating that I can't buff him up now. I guess until then, my KDF captain will just have to kick his scrawny little man-butt from one side of Omega Leonis to the other until he learns to toughen up (read: Cryptic please fix mods for cross-faction BOFFs).
