Not sure how this happened, but i think it was when i was lagging or something, and i went to promote one of my BOs. It gave me an error so tried again. Same thing a couple of times. Now my BO is max rank, and i can't train him in any skills even the first level ones.
I'm LT CMDR 6, she's CMDR. This is awkward. Is there a way to fix this without deleting her? Or will i have to just hang on to her until i'm high enough to train her?
It seems like weird things happen if the server's lagging out when you do stuff with BOs. I had an officer in OB that was over-promoted like yours. I have a current BO that managed to end up with two ensign ground abilities. In those cases, though, nothing became broken -- I could continue training them, and they'd use all the abilities they had available.
I'd suggest calling for GM help in-game. Hopefully they can fix the BO so you can properly use it.
