Yesterday's report returning null when it shouldn't.

Accessing ReportManager.Instance.YesterdaysReport returns null on the second cycle, when there is a report for the previous day.

It looks like todaysReport is not added to the dailyReports until night, so this code,

public ReportManager.DailyReport YesterdaysReport
	{
		get
		{
			if (this.dailyReports.Count <= 1)
			{
				return null;
			}
			return this.dailyReports[this.dailyReports.Count - 1];
		}
	}

should probably check for 0 not 1,

public ReportManager.DailyReport YesterdaysReport
	{
		get
		{
			if (this.dailyReports.Count = 0)
			{
				return null;
			}
			return this.dailyReports[this.dailyReports.Count - 1];
		}
	}

Noticed this because the insufficient oxygen generation notification won't trigger on the first or second cycle.
