These are some screenshots regarding the 3.1 Delivery Mission Bug. Here is the relevant frontier forumn page. I am using a PC. When I selected the reward in the completed mission screen, it did nothing. I clicked it several times but nothing happened and so I had to just leave it but it still displays in the Transaction panel as incomplete.
