Go to Catalog, add product to cart, everything will be fine. Soon as you add the upsell cart item to the cart it breaks itself. Even if you add the upsell items in the cart when cart is empty and try refresh page its broken?

What is expected?

Upsells have been and should just automatically go into cart if users adds them to cart.

What is actually happening?

I imagine the upsells are being added to the cart because if you do use the upsell feature, the cart counter stills counts up but must just be breaking itself as the cart then disaapears once there is a upsell cart product in there?

If you need to clear the cart to try again or testing just use '/clear' at end of cart url.

Also we're looking at cart.liquid file mainly
