Fixed: the cart could not be pushed with full boxes on it

Several of you reported that the cart would only slide a little in place, and that the wheels looked like they were sinking into the floor. You were right — and it was a bug, not a weight system. The cart doesn't simulate load at all, so a full cart should always push exactly like an empty one.

The cause: an open box and a sealed box are two different models, each with its own collision shape. When you place a box on the cart, the game tells the physics engine to let the two pass through each other. But the moment a box filled up and its lid closed, the model swap silently wiped that rule — and the sealed box's collision shape appeared inside the cart as a solid obstacle, shoving it around on every frame.

That's why filling boxes on the floor first and then loading them worked fine, while filling them on the cart locked it up.

It's fixed now: the rule is re-established whenever a lid changes, with an extra safety pass every time you grab the cart. Fill your boxes wherever you like.

Also fixed

A full box sitting on a shelf could push the player around — same root cause, fixed with it.

Thank you

This one came from three separate reports, including a player who went back and ran a controlled test to pin down the exact trigger. That turned a vague "the cart is broken" into a one-line fix. Genuinely appreciated.
