This has happened twice in a row. To complete the challenge, the wargs must eat the meat slabs in the instance which heals them. They will eat the meat when they are 3/4 low on morale. Well, they wont eat the meat. We took them down to 3/4 or lower and ran around for close to 5 minutes, stood on the meat, jumped up and down on the meat, and still they would not eat. Like I said, this has been twice in a row now. Has anyone else had this problem? Just curious and thanks!
