This has been happening to me since the living story update. Events in Wayfarer Foothill (specifically the wurm hunt and frozen maw) are giving me 500 exp, 10 karma, and 5 copper from gold medal. This happened to both lvl 80 (guardian) and lvl 39 (mesmer).
The wurm and frozen maw are chain events, at first few events in the chain would give me the normal rewards but after the first or so (it randomly changes) I get 10 karma for gold medal.
Anyone else getting this bug?
