Hey!
Using ZC 1.3.0.2.
When adding a product with an attribute (say for instance a shoe in size 10), I'm taken to the cart and the cart is populated as expected.
But if I then click on the product to add an additional size and clicks add to cart, I'm taken to the cart but the product is not added.
Removing the SID from the link back to the product makes everything work fine.
