Custom Shipping Carrier - stuck on shipping step ~ ...order=step2

[ZaxxaDK]

So i have run into a little strange problem, and i hoped somebody could help me out.

 

I have been working on my custom shipping module, and its been going great so far. But now i run into a "minor" problem:

 

Whenever i have choosen my carrier, and i press "ProcessCarrier", i get redirected back to the same step (order=step2) in the checkout process, and i have no clue why. I dont get any kind of information in my console or anything.

I obviously searched google, and some of them seemed to say that it was problem with the installation so i tried a fresh install - yet didnt help

 

So now im here, looking for a little help <3
