Describe the bug

I'm running MrCrayfish's Furniture Mod: Refurbished version 1.0.12 on a Minecraft 1.20.1 Forge server, and I'm experiencing an issue with the electricity system:

When I place an Electricity Generator and have a wrench in my hand, the usual connection outlines or UI feedback do not appear, and I'm unable to link power cables to the generator.
The generator itself appears to be on (fuel inserted and GUI active), but I cannot connect anything to it.

I've confirmed:

I'm using the latest version (1.0.12).

The wrench is the correct one from the mod.

No cables or appliances show any signs of receiving power.

The issue occurs both in creative and survival mode.

This happens only on a server — the system works correctly in single-player.

I’ve also tested without other mods, and the issue persists. It seems like the wrench’s functionality (connection indicators) is broken or not synced correctly in multiplayer/server environments.

To Reproduce

1. i open minecraft
2. i connect to server with my friend
3. the bug is still there even after restarting server

No response

I have the same issue, I can't connect any link with the wrench on the generator

I cannot seem to reproduce the problem. Do you still hear the sounds as if you were hovering the nodes or electricity links?

I too share the same issue.

Ver. 1.20.1
