Bug: Can't Automate Bottle O' Lightning In Modpack 4.3.5

Oct 30, 2025 by SLV Team 57 views

Hey guys! Let's dive into a tricky bug that's been reported in modpack version 4.3.5. It seems there's an issue with automating the creation of Bottle o' Lightning, and we're going to break down the problem, the steps to reproduce it, and potential solutions. So, buckle up, and let's get started!

General Information

First off, it's important to note a few key details about this bug:

No Mods Added: The user, DexxKnight1, confirmed they haven't added any additional mods to the modpack.
Consistent Issue: This bug occurs consistently in both single-player and multi-player modes.
Latest Version: The user is running the latest version of the modpack, which is 4.3.5.

This helps us narrow down the potential causes since we know it's not a mod conflict issue and it's happening across different game modes on the current version.

The Problem: Create Mod Deployer and Bottle o' Lightning

The core issue is that the Create mod deployer can't seem to use empty bottles on a charged creeper to obtain Bottle o' Lightning. For those unfamiliar, this is a method typically used with the Iron Spells and Spellbooks mod. The expectation is that when a charged creeper is nearby, the deployer should be able to fill empty glass bottles with the lightning effect, creating Bottle o' Lightning.

Steps to Reproduce

To better understand the problem, here are the steps to reproduce this bug:

Place a Charged Creeper: Position a charged creeper within two blocks of the deployer.
Supply Empty Bottles: Provide the deployer with a supply of empty glass bottles.
Power the Deployer: Ensure the deployer is powered and operational.

Unfortunately, even with these steps followed correctly, the deployer fails to create the Bottle o' Lightning. This is a significant issue for players who rely on automation for resource gathering and crafting.

Additional Attempts

The user also tried using the Item User from the Cyclic mod with glass bottles, but this method also proved unsuccessful. This suggests that the problem might not be isolated to just the Create mod deployer but could involve a broader interaction issue with charged creepers and bottle-filling mechanics.

Why is Bottle o' Lightning Important?

Before we dive deeper into potential fixes, let's quickly discuss why Bottle o' Lightning is a valuable resource in modded Minecraft.

Crafting Ingredient: Bottle o' Lightning is often a key ingredient in various advanced recipes, especially those from magic-themed mods.
Automation: Being able to automate its creation is crucial for players who want to set up efficient resource farms and production lines.
Utility: It can also have direct uses, such as powering certain devices or as a component in powerful spells.

Thus, the inability to automate Bottle o' Lightning can significantly hinder progression and limit the potential for creative builds and automated systems.

Potential Causes and Solutions

Now that we have a clear understanding of the problem, let's explore some potential causes and solutions.

1. Mod Interactions and Conflicts

One possibility is that there's an interaction issue or conflict between the Create mod, Iron Spells and Spellbooks, and perhaps other mods in the pack. Mods can sometimes interfere with each other in unexpected ways, leading to glitches and bugs.

Solution: Check for known compatibility issues between the mods involved. Mod developers often release patches or updates to address conflicts. It might also be worth testing with a minimal mod setup to see if the issue persists with only the core mods enabled.

2. Configuration Issues

It's also possible that there's a configuration setting within one of the mods that's preventing the automation from working as expected. Mods often have configuration files that allow users to tweak various aspects of their behavior.

Solution: Review the configuration files for the Create mod and Iron Spells and Spellbooks. Look for any settings related to automation, item interactions, or mob interactions. It's possible that a setting is inadvertently disabled or set incorrectly.

3. Bug in the Mod Itself

Of course, there's always the chance that there's a bug within the Create mod or Iron Spells and Spellbooks that's causing this issue. Bugs can slip through testing and make their way into released versions.

Solution: Report the bug to the mod developers. Providing detailed information about the issue, steps to reproduce it, and your modpack setup can help them identify and fix the problem more quickly. Check the mod's issue tracker or forums for similar reports to see if a solution or workaround has already been identified.

4. Charged Creeper Mechanics

The way charged creepers interact with certain items or machines might have changed in a recent update, leading to this issue. Charged creepers are a unique mob, and their behavior can sometimes be unpredictable when interacting with modded mechanics.

Solution: Investigate any recent changes to charged creeper behavior in the relevant mods. It might be necessary to adjust the setup or use a different method to achieve the desired outcome. For instance, there might be an alternative way to trigger the lightning effect or obtain Bottle o' Lightning.

5. Modpack Version Issues

It's conceivable that the specific version of the modpack (4.3.5) has an issue that was introduced in that release. Sometimes, updates can inadvertently introduce bugs, even if they're intended to fix others.

Solution: Check the modpack's changelog or update notes for any known issues related to automation or mob interactions. If the bug was introduced in 4.3.5, it might be worth downgrading to a previous version to see if the problem goes away. Alternatively, wait for a new update that addresses the issue.
