How to approach the decision
Editorial planning advice based on the confirmed systems above.
- Preserve the original save before changing anything.
- Record the first error and the last change that preceded it.
- Test on a copy with the relevant dependencies present.
- Report reproducible steps and version details to the mod author.
A mistake to avoid
Do not remove many mods from the only copy of a save just to see what happens. This checklist does not promise a specific crash fix.
What still needs live data
Exact numerical values, release-build menus and reproducible gameplay tests will be added only after verification.
Exact values and operating advice are added after testing against a recorded game build. Check the source date before relying on a number.
