I had my world with my friends and normal mods, in fact each one already had their houses made, even mines, chests and doors with retina were used, but last night an error occurred! I downloaded the world and I realized that it is only in the area where we have our houses that the world crashed and the server closed for us !! Does anyone know any command to remove blocks from that mod? or something similar !! I need help !!!
