No Cobblemon Bottle Return

Stops Cobblemon from returning an empty Glass Bottle when you use medicine via the Cobblemon GUI.
This is a tiny, server-side friendly mod for Minecraft 1.20.1 Forge and Minecraft 1.21.1 NeoForge that prevents the bottle from ever being added, so there’s no hotbar pop-in and no need to delete it later. All other bottles (brewing, loot, crafting) behave normally.

✅ Available for Forge and NeoForge
✅ Designed to be minimally invasive (only intercepts the Cobblemon medicine flow)
✅ Keeps normal gameplay intact (brewing/loot/crafting bottles remain)

What it does

• Prevents the empty minecraft:glass_bottle from being inserted into the player’s inventory when medicine is used through Cobblemon’s menu.
• Works by intercepting the specific add-item path used by Cobblemon medicine, then pretending the insertion succeeded without actually placing the bottle — meaning no visual flicker.

What it does not do

• It does not delete or interfere with bottles from brewing, loot, trades, crafting, or other mods.
• It does not modify Cobblemon’s healing logic, only the “return bottle” side effect.

FAQ

Q: Will this remove glass bottles from brewing or loot?
A: No. Only the “medicine returned bottle” path is blocked.

Q: Why not just delete the bottle afterwards with KubeJS?
A: Deleting it afterwards causes the bottle to “pop in” and then vanish. This mod prevents it from being added in the first place — no flicker.

Q: Do I need a different file for Forge and NeoForge?
A: Yes. Use the Forge build for Minecraft 1.20.1 and the NeoForge build for Minecraft 1.21.1.

Q: Can I restrict it to some medicines only?
A: Currently it targets the Cobblemon medicine add-path generically. If you need per-item control, open an issue.
