Items not showing up in cart if there are too many
Summary: terrapincollectibles reported an issue with their shopping cart where items are not displayed if there are too many. They have not provided additional details or responses to this issue yet.
One annoying bug that has been going on for years is that if you have too many items in your cart (50+), then then some items and sellers do not show up. I purchase 100s of sports cards a week, and this is an issue since API bids have another bug where they do not apply autopay correctly. So I have a scenario where a won auction will not be auto-paid, and it will not show up in the cart to be manually paid.
A lesser bug alongside of this is that if you click "pay only this seller" when the cart bug occurs, there is a good chance it will not put all of their items in your purchase and you have to make multiple orders and pay multiple shippings. The workaround for this is to not use the "pay only this seller" button, but instead click buy it now on any of the sellers items, which will then bring them all up in one order.
