I am soooo tired of fighting Tier 6 critters only to have them just vanish right before they die. I just got through fighting over a dozen encounters and only came away with 3 kills. One of those kills had some really nice items I would have liked to have gotten my claws on, but the loot window crashed so all I got for my trouble was a quick glance.

Is this an intended 'feature', or is it on the to-do list? It is severely reducing my enjoyment of the game, given I am primarily a hunter.
