I have now done 3 Grandmaster Lake of Shadows, all at platinum with not a single ascendant shard as a reward. This has taken me hours and is incredibly frustrating. I would love to know if there is a way to get my rewards back because I could potentially have [b][u]TWELVE[/u][/b] extra ascendant shards but instead only got three poorly rolled exotics. I know of at least 2 other players I have played with that have had this issue today. Terrible way to ruin what was a great idea for an event, very very disappointed.
