I noticed it since Ancestral Update beta, units (both my and enemies) are hidden until they come really close.
Because of this missile units become very little of use until you continuously scouting the area.
Once the units which you are pursuing become hidden (which doesn't take too long to happen) your unit stops pursuing in that direction.
Did anybody else notice this? I tried to play multiplayer with my friend and if it was me hosting the game both me and he were seeing this hiding issue, but if the host was he there was no such issue happening.
See the attached picture, the enemy is running onto me and he just appears only when he is very very close.
