When the AI moveto reaches the acceptance radius it starts jittering like crazy. Seen in linked video. Think it happens due to it continuously trying to moveto when in the radius but I don’t know how to fix this as it has to do the moveto first to know if it is in the radius.

Fixed by making the acceptance radius 0 and using a sphere trace as an acceptance radius replacement, and they only move if outside of it.
