Just this morning... I'm taking a fully loaded cart to my clay pit; the cart is not on my hip... attached me directly... it's attached via line.
I have no speed boost (hiking/run/etc) enabled, but I'm running ahead of the cart a big way... and the cart is slowly making time to catch up with me. (The Cart is moving w/o anyone in driver seat sort to speak... it's catch up to me (driver)... slowly)) Spiders, rabbits, crickets... all are crossing line that attaches me to cart... but cart keeps catching up so long as none directly interfere with it.
This has got to be a bug or glitch in the code.
