Here's a weird one for you all:
I came out of a Warzone (Alderaan Civil War), and all of a sudden my companion and the frame were gone. Problem is: at this point, I don't have either my starship or another companion, so I can't try those fixes. And believe you me, I've tried all the others:
Resetting the UI
Relogging
Restarting the game
Grouping and exiting
Running both a Flashpoint and another Warzone
Sending the companion on a crew skill mission
Along with most any other I can think of. I tried to have my companion sell some junk items, but it won't. It flat-out refuses.
See, the Companions and Contacts window lists T7 (the companion) like it's standing right next to me. Trying to dismiss it does nothing: the prompt shows up in the chat window but nothing actually changes.
All the fixes I've seen for this either don't work for me or aren't possible given my progress in the game. Am I just screwed and am going to have to try and solo everything until I can get another companion? I've got a whole planet before I get Kira.
Edit: When I tried resetting the UI, the companion cast bar flashes for a brief moment when the Ui comes back, but it doesn't fix the issue.
