Parts randomly starting to glide

Here is a video showcasing the issue. Notice how the part also snaps back after a few seconds

I have this tower constructed of 16x16x48 sized parts, 3 in a row like a jenga tower. Sometimes when a player stands on them, the part starts to glide around, causing the player to fall off a lot of times.

What i done to try and prevent this is:

  • Setting network owner to server (also for security reasons)
  • These are the physical properties: 3 density, 0.8 friction, 0 elasticity
  • I did try increasing the friction, but that slightly worsened it, so i reverted it.

The parts gliding seem to not replicate across clients, from what i observed when playtesting with 3 players in studio.

Do you have any forces like BodyMovers applied to the player?

No, no stuff acting on the player or on the containers, the only forces acting on the containers are the cars being thrown. (They are moved by calling :ApplyImpulse once)
