That is a different bug compared to the one on this thread. Post about that bug here: VehicleSeat Throttle/Steer oscillation on single tap of an input key during frame lag
This thread you’re posting on has to do with the seat becoming disconnected after getting into it and thus not accepting input. The bug you’re talking about is the oscillation bug. Two separate bugs, two separate threads.
The setting of network ownership fixes the disconnection bug, not the oscillation bug.
