I recently tried to do the keep of ganelon with somebody else. We finished defeating the black and white dragons but in the middle of that battle I died but I ported back in to finish the battle. After the battle I talked to king artorius and he told me to see the lady of the lake. When I went to see the lady of the lake, it told me to defeat the white dragon. So now I have to defeat the white dragon again but in order to do that I have to do the whole dungeon again. I just want to know if this is a glitch or what because I really don't want to do the dungeon again
