I have an enemy character with Seeker and AIPath components moving around a grid graph. When I enable the Constrain Inside Graph flag (to stop the enemy poking its head through walls) it starts seemingly randomly teleporting a short distance (1-2 units) sometimes when moving across an open area with no obstacles.
Sorry for the late answer. I have been traveling and have not been able to answer support requests for some time.
That sounds strange. Could you post a video of this happening?
Also, which version are you using?
