Okay, so I log in tonight, and in the course of my explorations, I noticed three things:
First, though the damage reported last night has been fixed, someone blew up a good chunk of Terribletwo18's stone cube, spilling the contents of his chests onto the floor. I recovered what I could and put it in a labeled chest in my house, and will turn the stuff over to an admin or Two as soon as I see one.
Second, in exploring Atlantis, I found a random pile of stuff, diamond armor, some building materials... I'm assuming someone died at that spot, then disconnected. These items are also in a labeled chest in my house, and I will turn them over to their rightful owner when the owner private messages me and tells me what enchantments were on the armor.
Third, someone had dug into the road leading to my store, and part of the store front (my bad for not protecting it, that's fixed) to build a swimming pool or something. I repaired the damage to the road and to my storefront, and protected my storefront.
What the heck is going on? I'm really starting to be really, really glad I put my farm so far out, but it's going to take away a major motivation to play if I have to worry about stuff happening in the area of my shop.
