In the Android App, if I open the close dialog for a question that I've already voted to close, the close options will simply be stuck loading forever.
This initially came up in version 1.0.26 on Android 4.4.2, and it's still present in version 1.0.49 on Android 4.4.3, both on a HTC One.
If I've already voted to close, I will never be presented with the close options, nor will I even be informed I've already cast a close vote previously, I'll just see the loading spinner indefinitely. When this happens, I have to wait for a while wondering if my 'net is being slow, or if I've already voted to close this question.

And here they are, still loading, a few minutes later:
