I already checked all the possible dummies, involved in his spells etc. All their sight radius' are already 0 : / And the 'sight radius' he currently has looks to be like 2200. I've gone through the triggers, there's nothing that seems be doing anything to do this. If there was a trigger doing this other than his spells it'd be affecting more units that just him, but i've looked through them.
guessing into the blue is just plain boring
