Umbraco version 7.3.8

Haven't seen this happen before. The day of this issue occuring we regenerated the dll and it's obviously disliked it somehow. Any ideas?

Before:

System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.
   at Website.usercontrols.course_dropdowns.CourseDropdown_SelectedIndexChanged(Object sender, EventArgs e) in F:\website\usercontrols\course-dropdowns.ascx.cs:line 117
   at System.EventHandler.Invoke(Object sender, EventArgs e)
   at System.Web.UI.WebControls.ListControl.OnSelectedIndexChanged(EventArgs e)
   at System.Web.UI.Page.RaiseChangedEvents()
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
   at System.Web.UI.Page.HandleError(Exception e)

   at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

   at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step)
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Umbraco 7 and below use Log4Net.

If you want line numbers in your logged stack trace you have to deploy the matching .pdb files. This was the cause in my example.
