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.
