Every command you enter has only the int limitation (number to 2147483647 (= 2^31-1) included). This might be first of all problematic if commands which use values of the data type long (up to 2^63-1) get added. But it causes some problems as well with commands that use the short data type (up to 32767 included).

This is for example the case with the Damage tag which is used for items and creates some strange bugs.

• Do for example

  /give @p stone 1 1143425434

  This is probably not such a big bug, but when doing it like this:

• Example Coal Ore (also works with cauldron and all blocks which have naturally no data values other than 0):

  /give @p coal_ore 1 1143425434
