I've re-run the conflux lost sector trying to trigger the completion so that I can do legendary and master runs, however the start banner/flag is not present. I've restarted my game and re-run the lost sector. I've verified the game files are okay. I had a friend with the start flag pull me into a legendary run, completed it and it is still not giving me the start flag. Every time, I kill the boss, kill all enemies, open the chest, and leave. No start flag for conflux. Please help.
