+ Mapillary (2.0.0-alpha.41)

I just released 2.0.0-alpha.44. This particular problem was fixed in alpha.43.

Hah, thank you for the quick reply :)
Saw a very similar exception a few versions ago, upgraded and it took a few days for it to re-appear...

I kept on trying to fix it at the source (I didn't want to add another if check in the UI). I finally gave up and fixed it in the UI thread in alpha 44.
