the last update had the following note
"Behavior of the monsters appearing in the ENM quest "Sheep in Antlion's Clothing" has been adjusted."
It looks like you have to kill the baby antlions now, instead of sleeping them and looking for the main one. My group tried to find another after sleeping one but we couldn't get the main one to pop. However, by the time we did kill the small one (it was like our fourth) we ran out of time.
Has anyone else done this since the update?
