User blog comment:Ujimasa Hojo/Chef Antoine versus Purewal Memorial Cup/@comment-4694083-20140801202943

Feeding Snowflake meat violates it... for whatever reason. I've done some research on this because I've missed the achievement despite trying several times, and that's what got me. However, this is just a general consensus that I've seen on several message boards/sites, not sure if it's intentional or correct, not confirmed by the devs or anything.

Not sure about Antoine's mission though. I just stay away from most of the survivors and psychopaths and focus on the missions to avoid anything screwing me up.
