Solved OnTick failing when I load my plugin

I'm trying to add this to gather manager instead of using it in my own plugin and OnTick seems to fail when I load the plugin.

Screenshot

The OnTick function

Code:

void OnTick()
        {
            if (RateMessagesEnabled)
            {
                dayNightCycle();
            }
        }

dayNightCycle function

Code:

private void dayNightCycle()
        {
          
            double currentTime = TOD_Sky.Instance.Cycle.Hour;
          
            if ( currentTime >= sunsetHour && FirstEveningCheck )
            {
                FirstMorningCheck = true;
                FirstEveningCheck = false;
                FirstNightCheck = true;                PrintToChat(string.Format("[<color={ChatPrefixColor}>{ChatPrefix}</color>]: <size={MessageSize}>{NMessage}</size>"));
              
            }
            else if ( currentTime >= sunriseHour && currentTime < sunsetHour && FirstMorningCheck )
            {
                FirstMorningCheck = false;
                FirstEveningCheck = true;
                FirstNightCheck = true;                PrintToChat(string.Format("[<color={ChatPrefixColor}>{ChatPrefix}</color>]: <size={MessageSize}>{DMessage}</size>"));
              
            }
            else if (  currentTime < sunriseHour && FirstNightCheck )
            {
                FirstMorningCheck = true;
                FirstEveningCheck = true;
                FirstNightCheck = false;
              
            }
      
        }

Variables

Code:

sunriseHour = Convert.ToInt32(GetConfigValue("Settings", "sunriseHour", "5"));
            sunsetHour = Convert.ToInt32(GetConfigValue("Settings", "sunsetHour", "19"));
            RateMessagesEnabled = Convert.ToBoolean(GetConfigValue("Settings", "RateMessages", true));

If someone could help me with this, i'd really appreciate it.

What you're trying to do is string interpolation: Interpolated Strings (C# and Visual Basic Reference)

 

Thanks for the help.
