While I do admit that the accessing of their chests is rather inappropriate of me, I've been a little suspicious of their activities, and as such kept a close eye on them whenever possible. I've recently looked through their chests and found quite a few items that I believe to have been stolen, specifically a few banners that you'd find at Ham's castle if you've been there before. Having gone through their other chests, I have also found the following (which I believe to have also been stolen): - 64 Diamonds - 18 + 28 Emeralds - 1 Golden Apple - Redstone Lamp - Coloured Wool - 2 stacks of Magma Blocks (they do have a nether portal but have shown no signs of ever mining on the other side.) - 64 + 47 Purpur Fruit - Several Glass Panes - 3 banners from Ham's castle - A couple of Daylight Sensors The coordinates of the thief's chests are: 6617, 56, 5944 If memory serves, I think the thief also has a friend, though I cannot be certain if he was aware of the theft or not.
