TorsoRootPart.rbxl (39.7 KB)

2 sets of 4 Humanoids
Blue Humanoids contain a HumanoidRootPart and have Humanoid.RootPart set to HumanoidRootPart
Red Humanoids don’t contain a HumanoidRootPart and have Humanoid.RootPart set to Torso
All humanoids have MoveTo set to the green brick’s position, updated every Heartbeat
Function included to set the humanoid’s network ownership to the server, can be removed for an alternative result.

Expected Behavior

R6 Humanoids without a HumanoidRootPart (Humanoid.RootPart == “Torso”) function as normal on both the live servers and studio.

Actual Behavior

R6 Humanoids without a HumanoidRootPart (HRP) (Humanoid.RootPart == “Torso”) function correctly inside studio, however do not function correctly on the live Roblox servers. Inconsistent behaviour is shown if the part’s network owner moves close to the humanoids without HRPs. However if the humanoid’s network ownership is set to the server, humanoids without a HRP fail to function completely on live servers. They remain functional inside studio.

I confirm this bug happens in my game too under the same circomstances. When the network ownership switches to a player, it looks like it gets back to normal.

This issue is affecting my game Bee Swarm Simulator as well, and causes most NPCs to either not move or move unpredictably. There are many cases in my game where the Torso is assigned as the RootPart and referred to so I’m hoping for a fix.
