My plot blew up.

[zs471]

I logged on today to find my plot blown up. Need proof? Go check courtyard, it is the plot right next to b_bob's corner plot.
I have no clue how the damage was done or by whom. It seems a bit similar to what happen to baileysara.
Luckily for the person who did it, they did not break any chests.

What I would like to happen:
A: An admin fixed my plot.
or
B: I can fix my plot if I get,
10 blue carpet
10 yellow carpet
48 oak planks
64 glass
48 stone bricks
2 beds
1 enderchest.

I would also like to know what happen. Thanks
