Sketch 3.83 - Sketch Palettes file released June 16 cannot load any new palettes
Hi,

thank you so much for creating this plugin and being so responsive on twitter and github. I am using sketch version 3.83 on a mac 10.11.5 (both updated to latest versions) and the latest version of the plugin. 

When I try to load a color palette into global or document colors using the plugin:

it opens a window to select a palette as expected, then when I select a palette (for example one of the 3 bundled palettes that you have in the github download) there is no feedback once I select the palette and it does not appear inside my color palettes.

Thanks again for your help, I have attached a screen recording video to take you through the process so that you can see for yourself.
