Delve nodes: unable to complete some nodes even after you complete the encounter!

Same. Two different Frozen Hollow nodes are bugged (Armour Smuggler's Stashes) - after exiles are killed on the node nothing happens, there is no loot and you can't open reward boxes as they are locked.

Logging out and redoing nodes doesn't help.

Same issue on Haunted Remains.

Same bug here, not great depth but same thing. Unable to complete the encounter. Tried the same node 4 times, unable to complete. Have not tried any other node, was thinking a waste of sulphite. Smuggler's Stash!
