I discovered a shipwreck an I went to go claim the loot, like most people. There were 3 chests And when I opened the first 2, It was fine. I went to go open the 3d Chest and once I did, the server froze used all of it's cpu and memory and then shut down. I tried to get an NBT copy of the chest which i did, It also crashed the server. Even breaking the chest wasn't working. I went into a single player world with the same seed, and then I opened the chest. the game froze up for about a minute, and then the chest opened. it was a treasure map, and some other garbage (6 books, 4 paper). I have no clue what is causing it. Plz help as soon as possible.

edit: we also tried commands to remove it. also crashed server :o
