Conflux lost sector not giving me start flag for legendary/master lost sectors
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.
Discovering all lost sectors on Nessus has worked for some:
