I'm new to BBO, and have only played two tournaments where my partner was a person. I understand that every four hands the pairs change. Yesterday on the last hand of two of the three rounds one person bid REALLY slowly and got to an impossible contract (7C in one contract missing the AK of clubs). Then they played REALLY slowly and the round timed out. The hand showed up as an average for a few seconds and then there was a message that the director had changed it to making the contract. Both times. Does anyone have any idea why that happened and how to protest/stop it? If you don't finish it should be an average, right?
