Don't ever use old surprise set templates.
I spent all morning making a 500 break surprise set with 8 Envelopes and checked it thoroughly several times before generating. I accidentally started the live a few hours early so I had to cancle it and thought no problem I'll just go back in and use the recent template spread sheet and just generated the breaks again but what I didn't realize was it tripled each envelope making a total of 24 envelopes and my first buyer hit envelope in first auction getting my top hit which was worth $500. Has this ever happened to anyone. I'm assuming I'm SOL.
