Guild Wars 2

Having issue with this. The tag says " Found by looting the Eye of Zhaitan while helping the pact capture the Promenade of the Gods in Cursed Shore".

Just did that event and killed the Wizard as the Pact retook the promenade, but the Eye was not in the mix. Does it appear elsewhere? (It can be found in different events.)

Anyone else have luck with this one?

Thanks

Believe the eye is before the wizard (after giant).
