when attempting to use the simple iron chisel on my server, nothing happens. However, the rest of the mod is perfectly functional (diamond chisel, wrench, blueprints). Can provide any necessary files and have tried a variety of different solutions, short of deleting the world file. I notice there's no config file, not sure if there's supposed to be one.

i've tried a complete clean install now, and the iron chisel seems to still not work. unsure of the issue as there are no residual files

seems to have been clientside, apologies for the ticket. a restart of the game client fixed the issue.
