Plot disappears when changing Target Variable:

[jarad]

Both at http://shinyapps.org/apps/corona/ and using the cloned repository on my local computer, when I change the Target Variable, the plot disappears. Even going back to the original Target Variable, the original plot does not come back.

Looks like the "Countries to Display" gets unchecked for all countries.
