My friends are huge richardwads.
Me and my friend, cancel, - the only ones that bought in alpha in another friend's server we play on- are building this epic castle. It's very epic and stuff. So we mine a metric crapton of stuff and end up with 11 blocks of diamond. We put these in our secured lockette chest. My richardhead friend -The server owner, not cancel- decides to break it open by abusing his OP. He sees the diamonds. He has destroyed all of our diamonds in lava because he thinks we were 'cheating'. Because you can't have that many diamonds according to him.
This is jut because he sucks at mining in the right layers etc. So now we are diamond-less. We lost over a stack of diamonds.
So me and that friend (cancel) sort of decided to burn every loving thing in the entire server down and blow every bit of stuff up that is close to that OP's house.
Gonna be fun.
