The issue about the SP campaign should be fixed now
Yes, it had not reset last time I logged in.
Now I get to farm all the loot, err... I mean face the challenge all over again
It had not flagged up as completed, rather didnt reset back to level 4.
I notice that I get about twice as much reward for killing a level 24 enemy with my level 70 build than my level 23 build, which was a suprise.
