Collision Sentinel - Crash Fix

Description

Collision Sentinel is an engine-level fix that teaches Skyrim to survive broken collision on modded meshes. Vanilla has no defense one bad mesh and it crashes or freezes.

Collision Sentinel catches the bad data at runtime and keeps the game standing.

And it doesn't just hide the problem it names it. When it catches a bad collision, it logs the exact culprit (full NIF path, FormIDs, cell and coordinates), so you can track down and fix the broken mesh instead of masking it forever. The lookup is read-only and guarded, so it can't crash while reporting.

Built for the heaviest load orders packed with custom meshes city overhauls, interiors, dungeons. On small, clean setups you won't need it.

Small SKSE plugin: no ESP, no record edits, nothing written to your save, safe to add or remove anytime.

Q: Is the source code available?

A: Not at the moment. The plugin is closed-source for now. If this changes, I will update the mod page.

Q: Is this CPU heavy?

A: No. The overhead is negligible. It adds a tiny safety check to an already-existing engine step. This is a stability fix, not a performance tax.

Q: Does it log the bad meshes it catches?

A: Yes, since 1. 4 it logs the full NIF path, FormIDs, cell and coordinates of the culprit. The lookup is read-only and fully guarded, so it can't crash while reporting, and each mesh is named only once. No setup needed.

Q: How do broken meshes look with this mod installed?

A: Nothing changes visually. The object looks and behaves the same. Collision Sentinel only neutralizes the bad collision value at the moment of the check so the game does not crash. It does not repair, hide, or replace the mesh.

Q: Can this fix bad texture crashes too?

A: No. Texture crashes are a different problem. I personally have not investigated bad texture CTDs. Usually textures are easier to fix by resaving or optimizing the DDS, and Crash Logger may help point to the offending file.

Q: Is this the same as Havok Fix?

A: No. Havok Fix deals with high-FPS physics timing. Collision Sentinel fixes a different engine crash path caused by invalid collision results from broken or unstable modded meshes.

Q: Will this fix all crashes?

A: No. It only targets one specific collision-related engine crash/freeze path. It will not fix bad scripts, broken saves, missing masters, bad animations, texture crashes, or unrelated CTDs.

Q: Is it safe to add or remove mid-playthrough?

A: Yes. It is runtime-
