experiencing significant bug in version 1.0.5

Hi – I upgraded a site to version 1.0.5 this morning. The site was in the midst of a sale and had a number of products with a sale price. Someone placed an order for a number of products and the price was zero. The payment notification email showed that the payment source was “Test Payment”

It turned out that every product in the store that was not on sale had been given a sale price of Zero. I downgraded to version 1.0.4 and all of the zero price sale items had gone back to their normal non-sale price.

We did have one customer who was helping themselves to a second order of “free” products while we were figuring out how someone was getting all of these products for free.

This is obviously a serious bug. The payment source was Test Payment – was this test code left in the plugin that wasn’t supposed to be in the final release?

Thank you for your assistance with getting this quickly fixed!
