Actually i just talked to MrBump on IRC, and he said that the problem would still occur in 0.3. The reason for it happening is because of the server. I proved this by choosing a server that was hosted by an anonymous gamer, and recieved the crc error. I then tried an official server, and that seemed to solve the problem. MrBump said that whatever it is, it probably has to with the ping or how the server is set up, can't remember exactly what he said but it had to do with the server! Anways good night, and a merry first night of the new year.
