Don’t Crash Obscura
A defensive crash-fixer mod for NeoForge 1.21.x that wraps high-risk capability and inventory interactions with validity checks and safe fallbacks.
Its purpose is to prevent invalid-capability exceptions and off-thread tracker crashes from taking down servers, opting for graceful degradation instead of hard failures.
What it does
- Shields common crash paths triggered during:
- chunk unloads
- capability invalidation listeners
- multithreaded inventory polling
- Adds validity checks before capability lookups and returns safe no-op handlers when dependencies misbehave.
- Catches and neutralizes tracker calls across inventory aggregation code, preventing cascading crashes.
Why use it
- Keeps servers online when other mods hit edge cases instead of halting the world.
- Acts as a low-noise, zero-config safety layer that prioritizes stability over perfect behavior during faults.
Compatibility
- Minecraft: 1.21.1
- NeoForge: 21.1.217
- Java: 21
- Mixin: 0.8.7+
Behavior
- Uses graceful fallbacks (no-op trackers / null handlers) instead of crashing the server.
- Introduces no gameplay changes under normal conditions.
- Activates only when fault conditions are detected.
