If your crash log screams D0020: Duplicate disaster spawn detected, you're in the right place. This error loves Java Edition but sneaks into Bedrock via Realms too.
Pinpointing the culprit is half the battle. Here's what sparks Double Disasters:
| ⭐ Cause | ⚠️ Why It Happens | 🛠️ Quick Check |
|---|---|---|
| Mod Conflicts | Fabric/Forge mods like WeatherStorms or Dynamic Surroundings double-trigger events | Run vanilla world – error gone? |
