Because there are too goddamn many event drops, and it takes too goddamn many tries to drop ONE ITEM. Like, am I the only one that has to repeatedly drag n drop an item before it succeeds? Sometimes it just doesn't register. My favorite part is when I FINALLY succeed in dropping one of those goddamn egg pots, only to pick up another one, refilling the spot that took 30 seconds to free up.
Another thing - trying to change equips on a map with enemies. Just refuses to work most of the time. Walked all the way out to your training spot but forgot to put on your drop equips? Welp, gotta go back to town and change.
