    So I have a map that we have been running on Vanilla Minecraft server with a few SMP mods. All of our mods were ported to Bukkit so we were going to switch to Bukkit. Long story short the server wont start cause it wont load the map. For awhile i thought it was a mod issues but then I tried something. I launched the map using a plain unmodded version of Vanilla Minecraft. It booted and remove all the extra block ID's from the mods. This worked fine. I think try to boot with and unmodded/no plugins craftbukkit1337 and I get the same error that I got when I was trying to use mods.

    The error is bellow. All i know is that the issues must be with Bukkit its self. Is there anything i could have done to the map to make it not readable by Bukkit? I have ran Chunkster against it with no help.

    It could be that you were using a mod that created a weird biome, and now that the mod was removed, that biome isn't recognized by bukkit/minecraft. Try renaming your world folder and restart your server, allowing it to generate a new, temporary world, see if it gives you that error again.

    Yeah it works if i let it create a new world. The only mods that I used were RedPower and BuildCraft. I know RedPower adds to the map but that mod is fully ported. I guess ill reach out to that mods dev to. Any other ideas?

    If its your world, then it's your world, not a TON you can do about it, unfortunately. If you've got backups, try restoring from a known-good. If you're able to open the map in MCEdit, see if it will let you delete the chunks around your spawn area and then let Minecraft rebuild them, see if that works. Really not much that can be done.

    Thanks. Just odd. For now ill just not switch to bukkit. My user base would not like to get the world wiped.

    I think chunkster would "repair" bad chunks, but map may be changed a little, where was bad chunks, there can be mountains or something..

    I tried chunkster. Didn't help.

    It's definitely a bukkit issue -- I just went from a plain vanilla server with no mods ever to bukkit, and am getting this same exact error. It seems like certain worlds bukkit doesn't like for some reason.

    Yeah I had to tell all the people on the server that if we wanted bukkit we would have to scrap the map. They voted scrap the map, still sucked.

    It was suggested above and I don't know if it will help, but you can try to open your world with MCEdit.
