Sounds to me like a mystery. You are certain it was trolled and not creppere'd by accident? I haven't seen the damage mind. Whoever left diamond blocks in my chest, thanks. For that kind act I added more chests filled with bread from my bread vault. Anyone is welcome to take as much bread as they need. Now on to this…
Just letting people know they're welcome to harvest my crops so long as they replant. I also offer a chest of bread for 1 diamond but you're better off just growing your own and I'm too lazy to deliver. It's near spawn next to a giant castle.
