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.
It's a 1.6 problem in general. I THOUGHT it was limited to SMP (not just bukkit either), but I'll look into whether it's also SSP or whether you just got unlucky.
Rather frustrating. Most people seem to be having less worrisome bugs, but this seems to be a bit farther out there. Hopefully whatever fix Notch comes forward with fixes, otherwise this inaccessible world will likely be the end of my minecraft career.
DISABLE THE NETHER! I had exactly the same problem and disabling the nether in server.properties fixed it for me easily hope I helped ^^
Thanks for the suggestion, but it doesn't seem to have worked. Still get a blue screen a millisecond after logging in, no console errors, just no screen followed by a freeze.
