Mine has not worked since I beamed at Drozana I still have this problem as well. My KDF and Federation characters still works on tribble. So I deleted them to create a new Romulan character, and he works. I want to be able to use my old Romulan again though..

I chose KDF, and his facial expression changed into something reminiscent of that that smug, yet aggressive Romulan expression that we see them do in TNG and DS9.
