Gear Improvements Last Longer – GILL
This simple mod changes the duration that armour and weapon improvements last to more realistic, not exaggerated values.
Both improvements now last for a full in game day (roughly 96 minutes) after which they wear off. The vanilla 15 mins was 3h 45 min in game time. A full day makes them more useful and actually worth getting, but also short enough to actively look for the places where we can make improvements when they wear off.
