We ran Kara last week and when the raid leader I had running it go upload there was nothing in that GuildRaidSnapShot.lua except for the guild roster.

Any idea how this could happen? Like if he didn't delete the old file from the week before or something?

Also in the bidding when you start the bidding do you have to manually end it, I ask because there was no bidding or item info in the file either.

As a side note, this is inside the wtf/account/savedvaribles folder, I made sure.

The file does not get data saved to it until you exit the game. If the raid leader crashed or closed wow without a proper logout this will cause data to not be saved.

Six Demon Bag
Jack Burton: Hey, what more can a guy ask for?
Egg Shen: Oh, a six-demon bag!
Jack Burton: Terrific, a six-demon bag. Sensational. What's in it, Egg?
Egg Shen: Wind, fire, all that kind of thing!

It also saves on a /console reloadui.

I do that after every transaction (boss down, grss capture, loot awarded).
