Hello jiGGO1;
Bug description:
On the forge server, does the sword block work fine. Normally does the blocking not work on a vanilla server. Is this correct?

How to reproduce:
Please Join any vanilla server and use the sword blocking.

Mod version: 1.20-1.0.5
Forge version: 1.20.1 - 47.2.0

it would be nice, if you add an check if the mod on the server installed.
