Dear development team,

I was hoping this wonderful plugin would be updated to MC version 1.17

When using the latest version of the plugin (v1.0.6) on 1.17 I encountered the following error.

[21:22:46] [Server thread/INFO]: kittygaming99 issued server command: /punish kittygaming99 [21:22:46] [Server thread/ERROR]: Fatal error trying to convert PunishGUI v1.0.6:net/bghddevelopment/punishmentgui/menu/slots/Slot$1.class org.bukkit.plugin.AuthorNagException: No legacy enum constant for GRAY_STAINED_GLASS_PANE.
