Hallowed Ground King Wasi Terrain Issue

I managed to get King Wasi hung up on several bits of terrain but then winkle him out to get him to the mine. However, now he's in a rock and can't seem to charge out in any direction. Since I think I successfully only targeted the real Queen in the first part, I'd rather not start all over :(

Update: It could not be fixed. I did restart, this time taking a friend with me and being super careful to stay in the clear area to kite the King (plus I got the Queen achieve by letting my friend beat up all the illusions without my input). Hopefully something can be done to prevent him charging into objects, there being so many objects in that room to hang him up with.
