Possible bug with monk epic Brother Balatin DL

[Xambick]

Was with an enchanter 10 hrs ago at DL to MQ the chardok metal pipe (enchanter), and my robe and KC metal pipe.(monk)

Killed about 6 placeholders then the epic guy spawned, no one else there.
Enchanter tashes then charms the mob, and hands in chardok pipe, and before I get to do any trade with my pipe and robe, the enchanter receives the robe reward with text from Brother Balatin

So how does this happen on a freshly spawned epic mob?

Shouldn't the epic spawn have a fresh empty inventory apon being spawned?

If someone has stuffed up their hand in at an earlier time the freshly spawned epic mob should have an empty inventory.

Thoughts?
