I seem to recall there was something different that triggered if you hunted, maybe the pack that sent in their order last? It wasn't a repeating pattern at least. Whoever hosted, I think, also had it that way to hide the number of packs.I think that might have been me. ;-)
It was frustrating, but it was actually a regular ABCABC pattern. I was only keeping it secret to hide the number of packs from team evil.
*shrug* Not the best of my ideas, I admit.
We also have the OY game when there were three packs but with an ABAB patern because pack C (me) was also undercover as part of pack A and B.
