DLC Still not working offline... Is this going to be fixed?

Title says it all.

Whenever my connection drops I get kicked out of DLC and transported back to Covenant Pass.
This has happened mid mission. Casino is then missing from Fast Travel.
If I start the game in offline mode Casino is also missing.

Is this going to be fixed, or can we look forward to all the remaining DLC’s to be online only?

Did you submit a support ticket for the issue? That’s one way to make sure it’s on the radar. I’m not sure how realistic it is to expect a patch over the holiday season, though, so you may need to wait until some time in the New Year for an update.
