#2

after testing without any wall/decorate it work again.(publish server)

still unlike in studio something might cause this to happen?

#3

setting AgentHeight lower actually fixing npc’s problem (right now)

#4

part of the reason could be that player characters on the server are always behind what the actual player sees
You can predict their position by adding their velocity to your move to position

humanoid:MoveTo(target.HumanoidRootPart.Position + target.HumanoidRootPart.Velocity*5)
