Hi!
Running "/help" results in an error and the only mod mentioned in the error message is fastcraft.
I'm running a server with a custom private modpack which was, unfortunately, not assembled by me. So it is possible that something else in the pack or a faulty config is interfering. But I don't know and since as I already said it is the only mod mentioned in the error message, I wanted to ask here in case this is indeed caused by fastcraft.
Here's the error I get (as you can see I'm using fastcraft 1.22, but as far as I can see there haven't been any changes made to 1.23 which would fix this if it is a bug in fastcraft):
