3 egged HT pendant

I think there is a reason they implemented it in that way (can only egg on 1st slot). It makes sense if Nexon is planning on gradually allowing HT Necklace to be egged more than once over time. For now, only the 1st slot can be scrolled with egg. If they decide to allow Necklace to be scrolled twice with egg, then they revise the code to allow 1st and 2nd slot to be egged (but not 3rd). If you tested this, perhaps you could chaos 1st slot, egg 2nd slot, and then get error msg trying to egg 3rd slot (my theory). Then, later on when they decide they'll allow HT Necklace to be egged on all 3 slots, that's when the 3rd slot will be eggable.
