Seimeni/ceres defense A.I. Broke after host migration

[Oroshe]

Mission started as usual, then at wave 6 host migration happened. 

Enemies wouldn't hunt us/open doors in spawn areas until the players came within visual range.

Then they would chase the nearest player. Not mass at the defense point. 

We decided to stick it out and the entire mission took 31 minutes just to get to wave 10.
