Well, in 4.7.1-4.7.3, we had problem with MoveToActor() function, which doesn’t really updated AI’s target destination when goal actor move. Anyhow Epic released 4.7.4 hotfix to solve this issue (https://forums.unrealengine.com/showthread.php?65340-4-7-4-Hotfix-is-live!):
Sadly, this only make the AI update its target destination periodically (I believe it’s 0.5 sec interval between each update). So right now, all AI will run in straight line, then make a sharp turn, run in straight line again, repeated, until the goal actor is reached.
I hardly see this as a good fix to the problem… So can someone help look into this issue again?
