Some spectre dont work anymore

Some spectre dont attack anymore, they just stand and walk along. They get hit and can die. I tried using "Gelit Zealots" (the eye of winter spectre), but they just act like training dummy for mobs.

I notice this behavior for most of the basic Faridun soldiers, when fighting them they are super aggressive but when you spectre them they only walk and until your character is hit then they start to get aggressive with the exception of the Faridun Impaler that seems to function great.

I also noticed this for a lot of the spectres I am using. In 0.4.0 I feel like I have to put in effort on ordering my minions to attack this mob at a distance or they just come back and form around me and do nothing. The mob isn't even at the edge of my screen too.

Compared to previous 0.3.0 where spectre aggro range seems much bigger and I feel like they take the initiative to combat any foes that are around or far from me reasonably.
