So I noticed this on the LIVE MAP, Went to investigate, and sure enough: Chunks are entirely missing. You fall right to the void. Also appears players have made bridges across but no reports yet I can see.
Have a few questions: What SMP is this? When were these taken? Are they still there? Try to PM a mod to get the quickest response to this thread as possible.
Acctully it could be any Snr Staff member as they have WorldEdit Its always him, he's practising how to do it to town so only /shop will be there and then the economy is gone!
