Plugin now attempts to contact several different name and skin apis before failing to generate a statue which should hopefully reduce any errors relating to "the api may be down".
Plugin api updated to 1.20; future versions of the plugin will try to use the latest version of the spigot api. If you would like a version of the plugin that works with previous minecraft versions, please see the releases page for plugin version 1.13 and prior (works with minecraft versions back to around 1.15).
Mangrove planks added to color map, and acacia now displays properly.
Significant performance improvements from asynchronously gathering skin images (i.e. your server will no longer freeze when running the command-- the plugin is now actually multithreaded unlike before (oops)).
Code refactoring and cleanup.
As always, if you are using worldguard or an economy plugin, ensure your plugins (like worldedit) are up to date.
