Today, when doing the Dead Hills "Into the Hills" zone, I experienced what I assume is a bug. When I clicked the item (Freshly Mangled Excavator's Pick) to see if I could put it into a collection, the merc in the group stated that it was casting a heal, which it did not cast. I clicked the item quickly about ten times, and with each click, the merc stated it was going to perform a heal. I suspended the merc, clicked again, and then received the message that I had already collected the item. It appears that item collection messages, at least on that particular item, have been replaced by merc speech.
