Describe the bug

Hello, I'm french : I translate my message by google translate ;) thanks

Hello, when I add an additional plugin, at times my worldedit no longer works (I can still use the selection with the ax) and the plugin sends me the message (in the following image) during execution of the command // set stone for example ...

And the console ;

.>.... [11:23:00 ERROR]: An unexpected error while handling a WorldEdit command

To Reproduce

1. Add a new plugin on my server (protocolLib or color-chat or dynmap)
2. Execute command //set stone for exemple (after the selection)

Expected behavior

That stone replaces the selected area (instead of an error message)

Screenshots

Already done (-> sorry to have done it instead)

Additional context

This error message occurred the 1st time when I had about 48 total plugins on my Minecraft server (I think this information useless)

THANKS YOU ;)
Help me please...
Bye !

Support questions should go to discord.

Ok, thanks
