Big Cart Fix

Fixes the unreleased B.I.G. C.A.R.T. from BOT10-Big_Cart.

What it fixes

Stops the repeated PhysGrabCart.ObjectsInCart() NullReferenceException.
Restores the cart value display so it shows the actual haul instead of a stuck placeholder value.
Reuses the vanilla cart value-screen behavior for increase/decrease transitions.
Copies vanilla value-screen sounds when a playable source is available in the loaded scene.

Install

Install this alongside BOT10-Big_Cart. The package depends on Big_Cart and BepInEx, so mod managers should pull those automatically.

For multiplayer, install it on the host. Clients may install it too.

Notes

If the log says Attached vanilla cart value sounds to Big Cart value display, audio was linked successfully.

If the log says No playable vanilla cart value sounds found yet, the display still works, but the current scene did not expose vanilla value-screen sound clips at the moment the value changed.
