It seems there is an unfortunate issue with the new off duty costume system, since the button is greyed out for KDF players due to them not having off duty costumes. From what I can tell, it's causing the rank 4 marauding reward boff, who only wears off duty costumes, to immediately reset its appearance when you try to make any changes to it.

Anyone else experienced this?

Yep I have same issue!

But it gets worse, the officer I chose was supposed to be a Science Officer with appropriate skll set.
However when I try to allocate skill points or give her a different ability I cannot make any changes at all.

Another bizarre thing is now that I have assigned her to my crew she is listed as an Engineer, despite the fact she has all science skills.

I haven't noticed the latter problem, though I might have avoided it entirely by picking an engineer myself.

What species did you choose? I'm having the costume issue with a female Andorian.

Human Science Officer - Female

Well, the only commonality between us is that we picked females. I suppose once more people having this problem start trickling in, we can better ascertain if this is a problem with the marauder boffs overall or if there are only certain ones effected.

Or, like, someone from Cryptic could give us some feedback. Whichever comes first!

Would be nice to get some dev feedback.

I was tempted to post the issue in the "Support > Gameplay Bugs" area but didn't want to get the "evil eye" from moderators for what they might consider as double posting. I did ticket my issue in game so maybe someone from Cryptic will eventually respond to it there. Given all the F2P stuff going on I am sure it would be a low priority issue to them, but it is annoying to have a BOff taking up a slot and be totally useless in it.
