What was the problem?
For the guild bank mod I went to WTF/Account/<my account name>/Realm/Sachmo/Saved Variables/*.lua
That's where I was looking for my grss snapshot too.
I had overlooked the saved variables dir in my <my account name> folder because there was so much crap in there.
I have folders for characters before they made it more heirarchical with realms and stuff. So it kinda got lost in the mix.
I know I know... if i used your tool it would have gone fine. I'm just paranoid.
