I will fix, update and optimize your minecraft bedrock addons
Mathias Santos
About this gig
Is your Minecraft Bedrock addon broken after an update, throwing Script API errors, or behaving incorrectly?
I can diagnose, repair, update and optimize existing Minecraft Bedrock Behavior Packs, Resource Packs and Script API projects.
I can help with:
- Script API errors
- Broken custom items, blocks and entities
- Manifest and dependency problems
- Deprecated components and events
- Minecraft version compatibility
- Addon migrations
- Performance problems
- Multiplayer issues
- Broken gameplay mechanics
- Code cleanup and optimization
My goal is not only to fix errors, but to leave your addon with smoother gameplay, better stability, cleaner code and properly working features.
I work with JavaScript/TypeScript, Minecraft Bedrock Script API, Behavior Packs and Resource Packs.
Please contact me before ordering and send the addon or describe the issue so I can review the scope and recommend the correct package.

FAQ
Do I need to contact you before placing an order?
Yes, I highly recommend contacting me first. Send me a description of the issue and, if possible, the addon files. I can review the problem and tell you which package best fits your project.
What do you need from me to fix my addon?
Please send the Behavior Pack, Resource Pack, scripts, or the complete addon files related to the issue. Also describe what is wrong, what you expected to happen, and your current Minecraft Bedrock version.
Can you fix an addon if I don't know what is causing the problem?
Yes. You don't need to know the exact cause. I can investigate the addon, identify the issue, and determine what needs to be repaired. Complex diagnostic work may require a larger package or custom offer.
Can you update an old addon to the latest Minecraft Bedrock version?
Yes. I can update manifests, dependencies, components, events, Script API code, and other outdated systems when possible. The price depends on the age, size, and complexity of the addon.
Does the Basic package cover any type of bug?
No. The Basic package is intended for one small and clearly limited issue. Multiple bugs, complex scripting problems, migrations, or large addon repairs may require Standard, Premium, or a custom offer.
Can you add new features while fixing my addon?
Yes, but new features are not automatically included in a repair package. Tell me what you want added and I can include it through an extra or custom offer.
Can you work on multiplayer and Realms addons?
Yes. I can investigate and repair multiplayer-related systems and make mechanics work correctly for multiple players when supported by Minecraft Bedrock.
Will you change parts of my addon that are already working?
I try to modify only what is necessary to solve the requested issue. If a larger change or restructuring is required, I will explain it before making major modifications.
What if the addon has more problems than expected?
If the addon requires more work than expected, I will contact you first. We can adjust the scope or use a custom offer for additional fixes. No extra work will be charged without your approval.
Will I receive the repaired addon files?
Yes. You will receive the modified files needed for the repaired addon, ready for testing in Minecraft Bedrock.
