If you haven't recieved your bounty even though you've filled the invoice there could be 2 possible problems (most likely):
1- You haven't entered a house number on your address.
2- You missed to sign the second signature space.
You should email the team with what you have missed.
This is ridiculous! I didn't put the house number on the address... Was that simply why I didn't get my rewards? The worst of it all is that they take years to respond to emails, will know when I'll have my rewards!

It was unusual method for bounty.
