One of the Mini-events (my term for neat little sequences that happen in the world but aren't counted as "Events" by the game) in Dahlgur Oasis is bugged.

Basically, you loot a chest and then a lone champion spawns behind you. Well... my champion had Health Link and he didn't have any friends. I was able to kill him as normal but I think that this behavior is not intended and should be fixed (but is very minor).
