The issue we are having is being unable to place any block down on the server. It will place then disappear. very frustrating cause it is a cool mod.

We use curse forge as our server and we play on 1.17 with optifine.

1. Fill out the bug template
2. Make sure the mod is actually installed on the server
3. This mod may have incompatibilities with optifine (We don't officially support it.)
