Where do you have to submit your dungeons run if at the final boss some random guy shows up?

Well i feel like if you did not do the whole dungeon with the other player you can submit it to solo section The boss fight doesnt take too long to kill even alone so i think its fine if someone randomly appears at the end

Well actually it was one of the bosses that does take a lot of time to do alone, it was the underworld crypt and when I entered it only took 2 more secs or so before the boss was down

Very late but I fixed the categories + added dxp. You can now type the name of the player when doing co-op runs.

Sorry for taking long time
