This is not a bug with BlockProt, but rather with AnvilGUI. Looks like it's failing to find/load the wrapper class for the API abstraction, which is very weird since I know it works for others (incl. me). Honestly not sure how this could happen, besides if something is corrupt on your end or you're using a weird Paper setup. Did you perhaps use any custom mappings, or are you using this plugin on a Fabric/Forge server?

Before it was a spigot server, now it's paper. I only use fabric in the game launcher with sodium. Wouldn't this be an NMS error? Could be about this https://docs.papermc.io/paper/dev/internals?

Solved using the latest release from github https://github.com/spnda/BlockProt/releases/download/1.2.3/blockprot-spigot-1.2.3-all.jar

I’m not really sure what went wrong. Maybe I loaded the plugin using a plugin manager instead of restarting the server.
