I noticed a bug in one of my older games since the physics interpolation update was enabled.The bug only appears when filteringenabled is off.
Reproduction steps:
When you change the CFrame of the humanoidrootpart or torso locally and then move your character the charactermovement is not registered on the server. This results in players not being able to see some other players move, while they appear to be moving locally just fine.
Edit: Update was rolled back so this is no longer an issue.
