I believe this is indeed related to the physics sleeping, I have it printing on tick if the physics mesh is awake, and it goes to false after a couple seconds, then when I try to thrust to move it it rapidly toggles between true and false, I have tried setting “Sleep Family” to Custom and “Custom Sleep Threshold Multiplier” to 0 but that has not solved this.
I believe I was using PhysX when it was in UE4 too yes.
Thank you.
