    This issue is primarily due to MSBuildTools class (part of project generation) immediately kicking off generation on [InitializeOnLoad], which kicks of Build and DisplayCancelableProgressBar. The problem, however, Unity editor apparently didn't get a chance to recover from reload and doesn't have some of it's items initialized.
