Steps:
We were trekking through Palace of the Dead, finishing off the final Succubus boss when all of a sudden my Internet connection begins to fail on me. My party members are left to fend against the boss for themselves after half the fight as i disconnect. Right after many attempts i finally manage to log back in, my party emerging victorious. However, they left the instance before i logged in. I obtained the credit for defeating the floor but now my file has labeled my party members "member not found" rendering us unable to progress any further into the dungeon. I don't want to put them under the torture and monotony of going back through those floors because of an internet connection on my end. Is there anything that can be done to salvage the file? Thank you for taking the time to read my report.
