Off by one with the /skyisland command

[Wetterquarz]

As I can see '/skyisland new' allows you to create 63 islands in addition to the starting island. The join and located subcommands take a number from 1 to 64. These don't seem to be shifted to the 0 to 63, which are the islands' actual indices. Consequently, it is impossible to join the original island and therefor to have the full 64 islands.
