Hi!
I know that the UE5.0 branch is still in development and all the bugs in UE5.0 do not affect FGearPlugin, but I’ll ask anyway. It looks like UE5 physics is causing or causing the wrong SubstepDeltaTime value to work, or causing the vehicle to go crazy at low FPS with both Substep and UpdateRate(Hz). Have you encountered such an bug? Maybe UE5 takes a different approach to calling CustomPhysics on FBodyInstance? This error exists both in UE5.0 (in github) and in UE5.0EA2
