Goldend pig's hard egg...

How can i open it?
i've tried to talk gold richie, it doesn't do any..

Having a Hard Egg in your possession should trigger a quest once you see Gold Richie in his vault(in which he gives you exp in exchange for the egg). Unfortunately, Nexon did not re-active the quest for the past couple (or few?) Golden Compass Events.

Long story short, Nexon'd.

Nexon'd.

Thanks ^^
