Forum:What triggers disappearance of weapons from open chests?

So, I've decided to see whether equipping Knoxx's Gold actually does increase quality of loot in the Armory or not, so I've just done my first run through the glitch, doing a spread sheet of every weapon and item by level required, rarity, and cost; naturally this takes some time for each run LOL. I figure I'll run averages on each category for a number of runs with and without Knoxx's Gold equipped and put this question to rest once and for all (my bet is that it doesn't do a darn thing, but I'm quite happy to be proved wrong).

Anyway, I came back down to where I started, and noticed that many of the weapons had disappeared. This was no surprise - I knew that weapons disappeared, probably on a timer of some sort.

What was a surprise was that the weapons hadn't all disappeared - only the low rarity ones. All the whites and greens were gone, but the blue, purple, and any orange ones I hadn't taken were all still there.

This got me wondering - what is it that triggers the disappearance of items? Is it a timer, and if so, how long does it take for the timer to kick in? And has anybody else noticed this "filter" effect, with low rarity items vanishing first? Outbackyak 12:10, June 22, 2010 (UTC)
