The egg merchants will randomly appear after you kill a mob. But I find this feature is very annoying and user-unfriendly. When he appears, I keep my normal attack. The egg list appear but tons of mobs keep attacking me. I have to spend extra time to close it and resume the fight.

And the Eggerton spawn very often, interrupting my fight so many times.

Can developers work on the Eggerton? Maybe let him spawn far ahead from the player so the fight won't be interrrupted.
