I logged on today which i havent done for a few days and i saw a few mobs at one of my buildings so i went to kill them. as i got closer i noticed a few blocks missing from the outside so i went in and i saw a hole was in the building. a big hole too. i dont know if there is a way to find out if someone did it or what caused it so i am posting here. My MC name is same as forums. Pictures:
