I had originally thought to report as a bug that I had somehow DROPPED OFF THE TOP 10 of the achievement getters leaderboard, but I figured that y'all wouldn't agree that that HAD to be a mistake. :P
(even odder, the first partial stack of meat I gulped to start on this achievement chain was exactly 11.)
Did we figure out a reason for this? I am also missing Protein Time and it sounds like others are too. The encyclopedia says it requires 11 raw meats, as opposite to meats. Are those meant to be two different things?
I think I figured this one out. Raw meat is actually different - it's fresh off the pig. So if you keep it in your bag a while and then eat it later, it doesn't count toward Protein Time. But if you nibble a pig and eat that right away, that counts as raw meat. That's my theory anyway, I'm pretty sure that's how I finally got the achievement. Others can see if that works for them too!
