Not entirely sure why the Halloween update is still out. I think it's because there was a long delay in releasing it, so they wanted to keep it around for a bit longer, but this is a little too long in my opinion. Regardless, the Christmas hub will be coming December 1st so it'll be changed by then, at least. Also, the lag is unrelated to the hubs/Halloween Havoc. It's still unknown what is causing so much lag, as far as I know. Try using a different ip to connect, as some of them are unstable at times. (This is also why we never recommend using number IPs to connect).
