A large party entered the 3rd area of the black dog moors. Upon entering this area we were ambushed on the transition by a group of lizard men.
We were standing as a group on the transition for about 10 seconds, and it did infact seem like an ambush spawn to me.
No one had time to wander off the transition, the ambush just appeared on us. I believe this might be a bug, because to the best of my knowledge ambushes are not suppose spawn on transitions. I apologize if this is suppose to be this way.
I took a screen shot of the location, so please PM me if I should post that as well.
