Raw rothe beef appeared in the Trog QA on a Trog Warrior's corpse. I assumed that they shouldn't have it.
Might also be worthwhile to add in deer meet or something as a replacement.
Again, I do not believe this is necessarily a bug. Most likely that Trog worked very hard to earn that meat and was looking forward to a delicious meal just as you decided to kill him. Hope you're proud of yourself.
Issue addressed.
