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.
