Did you set the property “Visibility Based Anim Tick Option” to “Always Tick Pose and Refresh Bones” in your skeletal mesh ? There is no rendering in the dedicated server and by default in UE4 the “Bone Refresh” (used for physics) will never happen when there is no rendering. That why it is working when you play as Listen Server because you can look your carriage. If you are curious, try to play as listen server but make the client (not the server) be the only one to look the carriage. You will have a surprise…
