No, I think that they make the victim have a full inventory, then they make him price check the valuable item.
Then they use the egg on the victim, causing the only inventory space from the item in the price checker be filled, then they boot the victim from the house, making the price checker close.
Normally this would make the item in the price checker go back to the vicktim's inventory, but as it's full, it gets dropped.
What we did was to smuggle the eggs out of Barbarian Assault and use them on someone who price checked an item with 1 free space in their inventory, doing that made the item they price checked drop to the ground since they had no inventory space.
Well they get 2 accounts to duel, one waits 15 min, other goes to forfeit tunnel but doesnt press to forfeit, just the interface pop up, then other gets removed from duel arena after 15 min while that one is on tunnel interface, later the guy who was removed goes to stake, and the one who was on tunnel press forfeit and they both get removed from duel arenas, if i get it right then that staker he staked logouts of sumthing and he gets loot ^^^
