Thanks for the report! The eggs weren't being deleted: your Auto HP setting was drinking them, because the Yellow and Green Easter Eggs are small healing items, smaller than a White Potion, so Auto HP picked them first. Auto HP no longer drinks items an active quest needs you to hand in. Spare ones beyond what the quest asks for can still be drunk. We also made the Maple Administrator's Easter Basket quest daily again, so you can get a basket for each of Mad Bunny's egg quests. Mad Bunny's egg quests can now be done once a day too. To re-test: collect eggs with Auto HP on, then visit the Maple Administrator in Henesys for a basket and hand both to Mad Bunny.
