Major Server Problem!

The server is having a major problem. This happened before on Logic Craft and the only fix was to reset the whole map ...

Code:

14:48:32 [SEVERE] Chunk (-32, -15) stored at  (-18, -13) in world 'LegacyCraft'
14:48:32 [SEVERE] net.minecraft.server.Chunk

that keeps spamming on the console like 10/s or more

I'm sorry that you will loose your items but we will replace it with new ones eventually

I know another solution but still involves a map change. I have saved a backup of the world but it has the same error. You can tell me if you want your house / kingdom to be put in the new world. I can do that using MCEDIT. But the problem is I don't know where it is.
