We have a DW20 server running 3.3.7 normally has it has always worked. ALL of our Infinity servers are updated with the 3.3.8 version and the Hammer no longer works for the change shape of the wedges. In-Hand - scroll works but the hammer is pretty useless as either right or left clicks just rotate the block.

This was corrected in 3.3.8.1 dev. It's been available for a while now, so I will release it as a stable build soon. You can either wait until your modpack incorporates the newer version, or just grab the development build and distribute it yourself.

Thank You for your quick response! This is my favorite mod :)
