one of my customer's order when he successfully order, it have 4 items, but after he process his payment (via Paypal), his order have 1 item disappear from database(even the grand total is changed)
I've never seen this happen, but two things come time mind immediately:
1. Are there any special characters in the name, price or sku of the product? Something that is causing the cart/PayPal handoff to dump the entire line?
2. Turn off "Override Customer Into" at the top of the form in Admin->Manage Addons->PayPal Payments
