EQ client crashes/closes with some kind of message about duplicate lore items that I was not fast enough to read. To reproduce: go to the bazaar place a "faded snowbound hands armor" into a tradebag use /trade and start trading drop another faded snowbound hands armor into the tradebag I have not thoroughly investigated, but it did happen for me 2 times before I realized what appeared to be causing it, and started avoiding it. I also had multiple snowbound legs armors, and it happened with them too.
It could be unrelated to the type of item. I just had /trade running, and tried to drop a new item into a full tradebag, and it crashed EQ. I've done lots of trading in the bazaar and never had crashes at all prior to the last week.
