In this update lots of bugs have been fixed.
In order to give that stability to the plugin,
I've split it into two versions.
On the one hand the version "legacy", for those who use the versions from 1.8 to 1.12 of minecraft. And on the other hand, version "1.13" which as its name indicates is for those who use version 1.13 of minecraft (1.13.2 included).
In addition, in each version the way of using the Head Mode changes slightly. For this, I recommend looking at the mini tutorial of the main page of the plugin.
