Router issue in 4.2.12 and up

[Kuubs]

When i use Jroute for my product url it gets appended twice

/product/product

instead of just /product

Unfortunately this issue exists in the latest virutemart as well (4.2.18)

It's the continue link in the cart, instead of just /product it will print it twice, so /product/product

Please show what you are doing rather than just saying "its a bug"

Is it code or template overrides you are working on?
