When checking in game stats, Moving Primitives is now always equal to zero. This started within a few months ago, around the time various physics improvements and or changes were being made, such as the change in assembly behavior to centralize. along with others: live-change-to-part-velocity-and-rotvelocity-setter-behavior, live-change-to-part-cframe-setter-behavior, upcoming-optimization-to-collision-detection-system-beta-test-on-mac-clients-soon, live-changes-to-motor6d-transform-and-motor-currentangle, to name a few.
Even in very physically substantial games, like @madattak 's Plane Crazy, this holds. As for every experience I have visited.
The reading is broken using Service Stats
Stats.MovingPrimitivesCountas well. (see developer) (see github api)
This is a metric error. It started a few months ago and is persisting as of 6/7/21.
