Someone decided they'd be cute and grief several areas of the town: Blocked the entrence with dirt, blocked the hall after the welcome wall with dirt, destroyed the welcome wall, blocked the main halloway with cobble stone, and removed a large portion of the torches(lighting) and random pits deep pits/wall sections missing everywhere.

I fixed most of what I saw, but I'd suggest others go in and check there housing for anything that may have been screwed with. I've already gone in a re-added tourches to everything i've seen missing and fixed the pitting/random missing blocks that I've seen. took me a good hour and a half to fix what I did.

Not sure If the SMP server has any logging, but it'd be prudent to find who did if it does.
