The first set of mobs in EoA are mispositioned.

Wandering Shellback 1
Wandering Shellback 2
Hatecoil Warrior 1
Hatecoil Warrior 2
Hatecoil Wrangler 1
Hatecoil Stormweaver 1
Hatecoil Warrior 3

Most of them are just shifted to the left quite a bit. See screenshots below for the way they're setup.

The mobs are correctly positioned, the blizzard map is just not correctly aligned with the ingame world - the road on the map is not where the road is ingame.
