.rdupe command resulting in “where’s donkey ?” Error message about familyfunpack HOT 2 CLOSED

Actually you can use a horse as a ride. In the init stage (first time you type '.rdupe') it will look for a horse/donkey/llama and say 'where's your ride' if none found. the 'where's donkey' message should be when typing 'rdupe' a second time next to a donkey/llama for duping, but none are found. This may have happen because you typed '.rdupe' once and did not finish the procedure. Try using '.rdupe reset' to reset the command, disable packet canceling and start over.

Using horse as your ride, you cant do .rdupe.
To dupe using the horse start with typing .rollback, enable packet canceller with player pos rot on, hop on the horse go to the donkey/llama and then do .rdupe.
