I've noticed a bug on my new play through yesterday, after the completing Korriban's little jaunt and talking to T3 to update the galaxy map for the new planets location the galaxy map hasn't seemed to update, so I can't continue the quest, nor can I travel to the planet and enjoy the new chapter. Has anyone else encountered this?
Edit: The issue was caused by having the Jedi Temple mod installed. Removing this fixed it and now all is well!
