Chaos Dungeon Lost from DC (Technical/Connectivity Issue)

Hi I was wondering if there was a way to get back a run which I lost because of network/connectivity issues from the server. This was really annoying because it limited my progress I was able to gain access to specifically new story content (because I would of had enough item level) if I was able to run the full chaos dungeon but with my DC I was not able to earn the Harmony Shard needed to progress in the story.

Furthermore, with such issues I believe an adjustment to the system potentially only give the player the rewards at the end of the run/when they confirm leave because this means they will not lose the run like in my case.

Kind Regards,
Me.
