Game breaking behaviour for local Humanoid rigs

Bug Reports Engine Bugs
#1

Reproduction Steps
Create a humanoid rig and parent it to ReplicatedStorage. Create a LocalScript in StarterPlayer which clones the rig and parents it to workspace and unanchors it. And then add a loop that sets it to MoveTo the location of the player constantly. Walk out of simulation range of the humanoid while it is following you (may need to increase player walkspeed). This occurs in Studio and the Live game. I made a demo of it here which is copyable: https://www.roblox.com/games/5197546788/test

Expected Behavior
I expect the humanoid to continue following the player as normal.

Actual Behavior
The rig first disappears, then appears to snap to a location relative to the player, as if it were anchored. It completely breaks the rig.

Here is footage of the bug occurring:

Try and set the network owner of the AI to the server, :SetNetworkOwner(nil)
AI Normally are on the server, however if this is a client AI then set it to the player, don’t let the engine compute this.

#3

I can’t. The server can’t see it.

Sorry, I should’ve specified it’s a LocalScript that creates the rig as well as controls it.

#4

Thanks for the report! Filed an internal ticket.

The test place doesn’t seem to reproduce the problem
Also after trying to reproduce by following STRs description, I couldn’t reproduce the problem

@TheSteelEagle , could you verify if you still see the problem

Here is an example of my testing
