I've been playing as my KDF character since he wasn't stuck anywhere until now. He's now stuck on the Qo'Nos shipyard. So far, it seems that the more social maps (DS9, ESD, Defera, Qo'Nos, etc.) are the ones that keep getting people stuck. Keep clear of them until Cryptic fixes this bug, and you'll be fine.
Captains Log Stardate blahblahblah, it's been three days since a transporter malfunction trapped me on Spacedock, having unsuccessfully attempted to bed that cute Ensign who sells Hyposprays and successfully drinking Club 47 dry, I find myself in the position of having to go where no man has gone before...that bush outside Admiral Quinns office
Been on STO since Beta and a fully fledged veteran with the scars to prove it.
you just need to log out and in again happended to me on holodeck
Just like helvetiamatt81 said, that doesn't work on Tribble. Tried logging in and out, and have been playing multiple days logging in and later out each time. If that worked (I wish it did ) my Fed character wouldn't still be stuck in the most ever boring place: Defera (my KDF character wouldn't be stuck in Qo'Nos either).
