Anybody have an idea why I get a 404 on the register link in the mod_virtuemart module when i display it? I've seen a few posts that talk about a bug but it's not clear to me if this is related or not.

All other links work as expected but for some reason this one gets mapped wrong.

Wrong SEF:
www.perfectmatchfavors.com/shop/index/registration-2.html

Correct SEF:
www.perfectmatchfavors.com/shop/registration-3.html

Now the link shows as the correct SEF but clicking it remaps to the incorrect SEF.

Again, this appears to be the only one so I suspect a virtuemart bug but any help is very appreciated.
