Shaman Epic sparkling gem turn-in

[Bleedalbeans]

Was helping a Shammy friend with his epic and have run into a brick wall.

We've done all parts of epic leading up to this point (already have black dire pelt even.)

On hailing spirit sentinel he faces shammy. Cons amiable. Shaman not invis. Turn in gem. Nothing. Got a rando to kill the sentinel and gem is not on corpse.

Petitioned and got gem back a month later assuming it was a bug. Same thing happened last night.

Faction still not high enough? No steps skipped that i know of.

Any ideas? Thanks for any help!
