Barrel duplication using Signs

[BAD7777]

A bug in the BreweryX plugin allows players to duplicate barrels by attaching multiple signs around a single barrel. Each sign is treated as a separate functional barrel, leading to potential exploitation and imbalance in gameplay.

---

Bug Description

The BreweryX plugin lets players effectively create 4 barrels from 1 by attaching signs on all sides of a barrel block.

---

Steps to Reproduce

1. Place a barrel supported by the BreweryX plugin.
2. Attach signs with barrel labels on all 4 sides of the block.
3. Observe that each sign is recognized as a separate barrel.

---

Expected Behavior

A single barrel should only be linked to one sign, regardless of how many signs are placed around it.

---

Actual Behavior

Each of the 4 signs around the same barrel acts as an independent barrel, enabling content duplication or confusing players.

---

Additional Information

Screenshots:

Server Version:

• Minecraft: 1.21.4
• BreweryX Plugin: 3.4.6

---

Impact

This bug can be exploited by players to gain an unfair advantage, duplicate contents, or disrupt the intended balance of gameplay.

---

Suggestions for Fix

• Limit the number of signs linked to a single barrel to one.
• Implement a check for unique barrel identifiers during sign interactions.
