Giacomo's Leash Fix

Giacomo’s Leash Fix removes the annoying ghost placement that happens when you right-click a fence while leading an animal and holding a placeable block.
With this mod, the client no longer predicts a block placement in that scenario—so your stack won’t visually decrease and then “reappear” when you open the inventory. The server behavior (creating/using the leash knot) stays vanilla.

What it does

No ghost blocks on fences when you’re the leash holder and right-click a fence.

Shift (sneak) preserved: holding Shift keeps the vanilla behavior.

Untying is unchanged: clicking the leash knot/entity behaves exactly like vanilla.

Client-side only: works on vanilla and modded servers; no server install needed.

Compatibility

Minecraft: 1.21.x (Forge).

Servers: Fully compatible with vanilla servers (client-side QoL fix).

Other mods: Compatible with most mods; anything that overhauls leash/fence logic might conflict.

How it works (technical)

The mod prevents the client from predicting a block placement when you right-click a fence as the current leash holder. Instead, it sends the proper interaction to the server, which runs the vanilla LeadItem logic (creating/using the fence knot). With Shift pressed, the mod does nothing—so vanilla placement (and sounds) occur as usual.

Installation

1. Install Forge for your Minecraft version.

2. Drop the mod JAR into your mods folder.

3. Launch the game. No configuration required.

FAQ

Q: Can I use this on servers?
Yes. It’s client-side only and safe on vanilla servers.

Q: Does it change gameplay?
No. It only fixes the client prediction causing ghost placements. All vanilla leash mechanics remain.

Q: Does it affect clicking the leash knot?
No. Untying/retieing via the knot behaves vanilla.

Enjoy clean leash/fence interactions—no more disappearing stacks!
