This iem is NOT <Exchangeable at All times> as shown in the description. I don't know if it's Pearl Abyss's bad English but if I can't exachnge the item after the event is over than this should not say that I can. Shouldn't I now demmand to be able to exchange it?

BDO in general has an extremely bad way of explaining what they mean about almost every item in the game and this is very frustrating especially for new players. If an item would be expiring why not having the expiration date in the description, instead of repeating the same useless paragraph of how some energy is streaming from it? Pearl Abyss, I understand you need clicks and web trafic, but please stop sending us to your website tfor absolutely every little thiung to spend hours there just to figure what is going on, when you can show it in a very simple way in-game. 

its a small indie company give them some slack!

theres no event npc for past event items i think ff14 has 1
