The bug is when you upgrade an old pre-patch version item by cubing, the entire game crashes and crashes all other games that share the same IP. There are people maliciously abusing this for fun and when this happens, the entire Asia server is completely down with no available games and users are unable to create games. This problem mostly exists in the Asia server.
I don’t think they are going to fix this. Why doesn’t this happen on the USEAST server? Maybe you can play on that server. Obviously not as good as a closer one, but might be your only hope?
