When i try to use this mod on a LAN server with my brother who doesn't have the mod installed (he is using Vanilla Minecraft), he gets this error when he tries to join my world:

**Connection Lost

Unsupported (vanilla?) client!
This server requires modded client to join!**

I'm using Quilt Loader on version 1.20.1 of Minecraft.

No response

currently rewriting the mod from the ground up (90% done) so im gonna close this issue as it will likely no longer be relevant
