Was on last boss on VCoS.
Member left as he couldn't manage it so I went to sue Group finder to get new member.
I accidentally misclick the dungeon but didn't notice, we then all got transported to Darkshade caverns without being able to decline and when we ported back to CoS it had completely rest.
Could dungeons not reset like this, as it makes a simple misclick make you want to punch your monitor through.
