So the other day, I and other party members got poisoned in one of the new 4.4 bits of content. I want to say Arboretum (Hard). So I decided to use an Antidote to clear it and give the Healer one less thing to worry about, since I saw it had the curable line.

But even though the Antidote went off, I still had the status. Is this normal? Is there some kind of difference between statuses that can be removed with items and statuses that can't? I'm not entirely sure why this distinction even exists since it makes status effect items less useful than they already are.
