i saw a post to this issue earlier and its happening to me, it started earlier today during arena super inconvenient and its been buggy ever since, i sent in a ticket and the reply was to clear my cache cookies and anything else i did so a few times, and its still happening, the items would show up for a split second and then disappear i have switched browsers to try it out and its still bugging

first google chrome and then firefox, i dont believe in internet explorer

and also because of this i cant harvest my crops in my farm, and i cant finish any quests that require an item to turn in, i get no bonuses in battles because it doesn't show any of my equipments
