Hows the andy glitch work?

[FraterPerdurabo]

Copy/pasted this off diabloii.net

So, I couldn't find a final answer to this question, so I decided to do a test.
It was done on /players8, after each session, the character was renewed from backup. I did never actually go to 2nd act.

Results:
1) First (quest) Andy kill, then clicking on Cain, then save & exit, new game and Andy dropped crap (gold,potions)
2) Andy first kill, talking to Warriv, save&exit, next game - quest drop (to be sure, I have done 2 other runs - with no junk/gold)
3) Andy kill, talking to all NPC, but not with Warriv, exit, normal drop (gold, antidote)
4) Andy kill, exit, Warriv, normal drop (gold, potion)
5) Andy kill, all NPC including Warriva (the last one), exit, quest drop (no junk/gold in next 2 runs)

So to activate Andy drop bug, you need to talk with Warriv in the same game when you kill Andy for the first time. It is not necessary to go to 2nd act.
Someone maybe already know this, I want to share with those players who didn't know this too.
