Mods compatibility issue

🐛 Error Report: Addon/Mod Compatibility Issues in Minecraft Bedrock 1.21.111+

Game Version:

Minecraft Bedrock Edition 1.21.111 (Official Release)

Platform(s) Tested:

All supported Bedrock platforms (Android, Windows, iOS, Consoles)

Category:

Addons / Resource & Behavior Packs / Marketplace Content

📌 Summary

After updating to 1.21.111, Minecraft Bedrock shows major addon compatibility issues:

Performance has noticeably improved compared to older builds ✅

However, most addons (even those marked as 1.21.111-ready) cannot be used ❌

Even paid Marketplace content is affected, becoming unplayable in new worlds

❗ Expected Result

Addons updated to 1.21.111 should load correctly in worlds

Older addons should remain usable with at least partial backward compatibility

Marketplace content should always remain functional after updates

❌ Actual Result

Addons fail to load even with all experiment features enabled

Error notifications appear during world creation when addons are activated

Both community addons and Marketplace DLC become unplayable

Packs that previously worked without issues now fail to initialize

🔎 Steps to Reproduce

1. Update Minecraft Bedrock to 1.21.111

2. Import any addon or resource/behavior pack (community-made or Marketplace)

3. Enable all available experiments

4. Create a new world with the addon activated

5. Observe: Error notification appears → world fails to create or addon fails to load

⚖️ Why This is a Critical Issue

Minecraft Bedrock’s identity as a sandbox + creative platform depends heavily on community addons and Marketplace content

Breaking paid Marketplace DLC is especially damaging for player trust

Compared to Java Edition, Bedrock now feels more restricted due to stricter schema/manifest enforcement without migration tools

This undermines player creativity, modding freedom, and the value of purchased content

📢 Suggested Fixes / Developer Actions

1. Restore backwards compatibility for older addons where possible

2. Provide migration tools or auto-conversion for outdated pack formats

3. Test future updates against Marketplace content before release

4. Publish detailed changelogs & documentation for addon creators

5. Add a compatibility toggle (e.g. “Legacy Addon Mode”) so older mods remain playable while developers adapt

🙌 Closing Notes

Minecraft Bedrock 1.21.111 fixed performance issues but unintentionally introduced a much larger problem: addon and mod compatibility is broken across the board.

This issue must be prioritized because:

It affects all platforms

It impacts free community addons and paid Marketplace content

It risks breaking trust with the playerbase and addon creators

We request urgent attention to restore both stability and compatibility in Minecraft Bedrock.
