--- Comment #14 from fiesh at zefix dot tv --- Bounty: EUR 150 I'd like to try something new and place a bounty on this issue. In order to collect it, you have to provide a patch that is accepted into 4.9 and 5. You also need to be able to write a bill with explicit VAT (we are based in Germany). Alternatively, I'll donate the money to any charitable use of your choice, again subject to requiring a receipt from the charity receiving it.
