I ran the mission and got to the end. I had a romance with Theron going before he ran off and at the end we patched things up and got engaged. Once the cutscene ended I was awarded his new appearance and armor but I can't get Theron isn't available. He still shows in the Contacts section of my Companions window but is unavailable for summons.

You think this surprise maintenance shut down has something to do with the bugs?

I know in part it's due to the Conquest resets. That much is on the DevTracker Forum

I have the exact same problem, I have sent a ticket but got no reply yet. I have done this fp 3 times and i have only bugged on my character that romanced him. Would love to know how to fix this so i get my idiot spy boyf...fiance to return.

Glad I'm not the only one. I put in a ticket and got back a dumb answer like I had another chapter open (which i opened after the FP) and they closed it. I put in another ticket and posted here.

I had a chapter open at the time i started Nathema but it was a repeated mission. Did they actually fix it for you? Did the fp on a character that had no chapters open and she got the companion Edited May 5, 2018 by Jodstaimpslayer

No fix yet.

I got a reply 5 days ago telling me i had to complete the open chapter (chapter IX of KOTFE) and it will update automatically. Tried this but the last cutscene bugs out due to the progress of Nathema so i changed it to another one and completed it and still nothing. Sent of a ticket that day now 4 days ago and still have not received a reply about my issue.

They fixed it! :D:D:D:D:D:D:D:D:D:D:D:D:D

Now my OC has her man back, just gotta do the same thing on my alt.

How did they fix it? Because I had a similar issue where my Theron romance got cancelled and didn't carry onto the Nathema flashpoint. I tried replaying the chapters but I also got stuck on the last bit of the last one. It bugged out and I could progress...

 

Did sending a ticket help? Because I sent them one and got no reply...
