On two consecutive characters now my main solo quest line has broken.

First on my psyker midway through the saving Thorne line.

Then on my second character a sniper on the Hunt for the martyr at 4/7.

The “travel to next quest” button is broken.  And there is nothing on the star map.  I can’t speak to anyone on the command deck either.

I’ve tried restarting, verifying files on steam and fully reinstalling. All with the same result.  Can anyone help?
