Problem/Bug Entity Glitched

Once I closed my server and then it doesn't want to start again. That's pretty much it. I can't really troubleshoot it as I don't know much about bukkit servers. I add and image from the console.

All I tried was using commands - "/butcher" and "/killall" but the command isn't even coming through.

Do you mean that?
I'm sorry if it's the wrong thing.

 

@ChocolateHusky
Have you tried deleting the world? (after backing it up if you want to keep it of course)

 

@AlvinB
Well, I know that deleting the world would help with the bug, but if I could delete that save I wouldn't ask here.
I've spent very long time on this world and I would want to get it back.
Maybe some option in MCEdit?

 

@ChocolateHusky

This tells me that the something with the actual file is busted. I'd be very surprised if this file is recoverable.

And on another note, why the hell are you still using 1.6? It's more than 3 years old. The newer versions contain lots of bugfixes aswell as new features. Not to mention it's close to impossible to give support to a version that you can't even obtain anymore.

 

@AlvinB
I'm using 1.6 because one of my computers that my friend is playing on is a really old system (yes I plan on upgrading it, I just don't have the money yet). The newer ones are unstable/won't work at all.

@timtower
If I open the save it's not doing anything by itself. Should I try and reload some of the chunk/s?

 

@ChocolateHusky
Do you see your worlds content when you open the world in MCEdit? If you do, try simply saving it, which might make it work on the server.

 

@AlvinB
Yes I see the world's content in MCEdit, but saving it didn't do the job. The same error as always.

 

@AlvinB @timtower you'd have to use MCRegionFixer for this, but with the severity of that error, it may not help. https://www.spigotmc.org/wiki/using-the-minecraft-region-fixer/

 

@Tecno_Wizard
Meantime I'll try it, could you explain what is the error actually and how could I prevent it in the future (if it's possible to prevent it at all)?

@AlvinB @Tecno_Wizard @timtower
Okay guys, seems that fooling around with MCEdit worked.
I selected few chunks around the two entities that got "bugged" (there were two - a pig and a chicken) and then killed all the entities.
The server started up and then I joined no problem.
