The immediate concern in competitive multiplayer circles is whether players can abuse the arm glitch to interact with remote objects, strike opponents through walls, or manipulate hit registration.
In almost every scenario, the stretched arm is a purely client-side rendering artifact. Roblox architecture relies on a client-server replication model. The server maintains authoritative control over the HumanoidRootPart and standard character spatial hitboxes. When an arm stretches across a map due to a mesh deformation glitch or animation desync, the underlying spatial query for damage calculations does not automatically stretch along with it.
If a player attempts to punch or fire from the tip of a distorted arm, the server validates the raycast or collision box from the character’s actual physical coordinate, not the distorted vertex position.
There are, however, edge cases involving custom ragdoll scripts. In experiences where developers replace the standard humanoid state with custom physical constraints upon death or tumbling, a violently stretched limb can generate extreme physics torque. If collision calculations remain active on the stretched mesh, the rapid expansion can knock surrounding players aside, catapulting them across the game environment in a classic physics fling.
