So it seems my server's world has become inaccessible since updating to 1.6.4. I've seen numerous people say 812 can run 1.6.4, but I've encountered the apparent problem that my entire world freezes. I've tried the world on SSP, and it still freezes. My question is whether or not bukkit is what's causing the problem, or my world has otherwise become corrupted by 1.6.4. Has anyone else run into an instant freeze issue? The server itself will run just fine, but when I sign in, it's frozen instantly, giving me only the sky to look at.
