For some reason, my server's chunks are randomly being replaced. This has happened on 3 maps now. I believe this is an issue with CraftBukkit and not any mod as it was occurring when we didn't have any mods. Anyone have an idea of what to do?
I think I have had the same issue earlier today. There ware a couple of high "mountain" chunks in the middle of my house/garden. First thought was my map is broken but maybe this is really a problem with CraftBukkit.
For me it's General, Permissions, LWC, MinecartMania (+Addons), MyHome, Whitelist, Worldedit and Worldguard runnig on CraftBukkit #164. But as Leech said it also happened without any plugin installed.
