There are only two problems that I know of in that version. What you call buggy may well be just that your products are not ready for the new google rules.
The new google rules do impact what you have - not the mod itself in that way. He simply coded in things to prevent your products from getting rejected by google and he actually didn't go far enough.
Such as your feed will get rejected if your image has an ampersand in the name or use of ampersand in the product description.
It's a free mod - done for free by Numinix and supported for free by me. You want to pay someone to set you up correctly? That may be the only way you are going to get it working for you if you are having problems.
If you have a real bug, then let us know.
