      Situation: On use of the /clone command for a relatively small number of blocks, players are kicked with an error message after a seemingly random amount of time. At least one player is left online with no problems. If this player disconnects and another connects, the new player is the one who does not get kicked. If all /cloned blocks are removed, the error stops. Attached is a text document with an example of the clientside error and the serverside error.
      EDIT:
      Command used:

      /execute TheMemeWhale ~ ~ ~ clone X1 Y1 Z1 X2 Y2 Z2 ~ ~ ~
