PhysGrabCart.CartMassOverride, PhysGrabObjectImpactDetector.FixedUpdate) and every cart field the mod reads are unchanged in v0.4 — recompile is sufficient and behavior is identical to 1.0.2 on the new game build.CartMassOverride adds twice the summed mass of items currently in the cart's tray, so an empty cart stays at vanilla 4 and a loaded cart scales proportionally with its payload. Replaces the old flat 6x multiplier, which over-weighted empty carts and under-scaled very heavy loads.rb.mass change at PhysGrabCart.Start.
