API Version | It wasn't possible to use 1.13+ materials as the arrow material or for the resource pack arrow. This is because the plugin uses the 1.12.2 API version. Without upgrading and making a ton of changes it was possible to fix this by simply specifying the plugin version as "1.13". I've tested the plugin on 1.8.8, 1.12.2, and 1.15.2 and it is working fine. If this causes any issues please let me know as soon as possible.
