Hello, I've been playing minecraft for a few years now. I've played mostly in faction servers, I've constructed every base so far in a single way, knowing all my weak spots and etc. I've perfected the raiding, but never in my lifetime have I seen a raid like this. My base is in the end, the hole showed in the pictures is aprox. 12 blocks from the border, at the floor. No territory has been claimed from us, the surrounding obsidian blocks have their health at 100% which suggests that there was no blast involved in the breaking of the block. If there's anyone that can explain to me how can this block be broken without abusing commands, I'd give that guy a medal. I attach 2 pictures taken at the "crimescene", if there's in need of more, tell me. Please, look into this because a couple of days of hardwork has gone into nothing.
