Version 2.1.0

The mod now has more sandbox options where you can edit:

• Normal Zombie Sight: The zombie sight level set under normal conditions.
  
• Reduced Zombie Sight: The zombie sight level set during night or fog.
  
• Minimum Darkness Level: The minimum darkness level for zombie vision to be reduced.

• Removed debug mode to prevent console spam.

Version 2.0.0

The hours that affect zombie sight now dynamically change with the seasons of the year. For example, during Winter it gets dark earlier, meaning the zombie sight setting will be updated earlier too.

This also means that I've removed the sandbox options for night start hour and night end hour, as you shouldn't need to adjust it manually anymore.

Thanks to @BreakUrSelf and @Æon for the suggestion!

Version 1.1.0

Zombie sight is now set to poor if it is night time or if it is foggy, reverting back to normal at all other times.

Thanks to @강남스타일 and @Siodog for the suggestion!

The mod now has its own section in the sandbox options where you can edit:

• Night Start Hour: The hour that sets zombie vision to poor.
  
• Night End Hour: The hour that returns zombie vision to normal.
  
• Minimum Fog Intensity: The minimum fog intensity for zombie vision to be set to poor.
