TitleLinks broken or bugged? Need help.. "Could not find ModernFrame target"

[thedonmon]

Hello, so far everything has been working flawlessly and haven't run into any issues. However, my MainWindow.xaml page has been messing up and will not navigate to the "/Pages/SettingsPage.xaml" page. The application crashes and tells me it cannot find the ModernFrame Target etc.

I have followed all tutorials for 4.5 and my MainWindow.xaml page looks exactly as it is supposed to. Are there any suggestions on how I should fix this issue?

If I move the <mui:Link></mui:Link> tag inside of the <mui:ModernWindow.TitleLinks> to the <mui:ModernWindow.MenuLinkGroups> group you can navigate to the settings page perfectly fine. However I do not want Settings in the menu, but near the top of the application. Code for reference:

    </mui:ModernWindow.TitleLinks>

    <Rectangle HorizontalAlignment="Center" VerticalAlignment="Center"

</mui:ModernWindow>

I ran into the same thing - basically adding any content to a ModernWindow can prevent the TitleLink navigator from finding the navigator frame. I'm sure there must be an approved way to extend a ModernWindow so the frame doesn't get displaced from its expected location, but I didn't work with it long enough to figure it out.
