Ya know.. that looks like the place I bombed.. was it by chance inside the side of a mountain (the entrance)
If so.. yea I blew the crap out of that place, I would ask how you came across 44 stacked Golden Apples (considering you can't stack them) but I imagine it doesn't matter.
Anyway, let me offer you advice the next time you construct a base.
A. If you build a huge structure (I know you didn't, but some of the tards on this server do) Don't put your main base inside of it, I don't care if you think no one is going to go out there and find it.... It's extremely easy to login, and pick one direction and run that way.. and unless you magically made materials appear out of your ***, You're going to do something to the landscape that's going to be noticed. Plus, If you by chance do build something, and it survives, someone else might build something near that structure, and I find a base out in the middle of no where, I'm going to continue on in that direction looking for more.
B. If you build inside the side of mountains, don't put torches near the door.. Hell don't have any light visible at any point near your entrance, I happened to find your base (if this is the one i'm thinking of, it had long stairs) by running to the top of a mountain at night, and looking around, and what do I see. a Lit area on the side of the mountain, of course i'm going to run over there.
C. If you have a base, and still don't follow the first two points, at least hide your crap.. If I walk in the front door, and you have bloody signs and chests right there, and I just walk around stealing everything, that's not really hiding crap.. If you guys ever actually manage to find my base (i'm banned now for some reason as well.. probably for blowing up your house)... You will not see any chest's, why? Because i've hidden them around the area...
So in closing.. Distance is not a reason to be sloppy on building a base.
PS, if it's happened 5 times this month, YOU'RE NOT BEING SNEAKY
