Fix Perish Rate is a Vintage Story mod by Marieldril. Fix Perish Rate removes the sea-level check from food spoilage, making cold storage work consistently at any elevation in Vintage Story.

Why this mod is worth installing
This utility suits players who build refrigerators, cellars, or food stores far above or below sea level. It is especially useful when a mountain base should preserve food as reliably as a lowland one.
What Fix Perish Rate adds
Fix Perish Rate changes the calculation used by in-world containers when determining how quickly food spoils. It removes the dependence on the world's sea-level position, so altitude no longer unexpectedly affects the perish rate.
The result is more predictable food storage for elevated settlements and unusual builds. You can place a refrigerator or other preservation setup on a mountaintop without the mod's sea-level check interfering with its intended behavior.
