Issues encountered when folders don't exist

The default folder for App Projects pointed to a network path that no longer existed. Instead of any kind of warning about this, I encountered the following:

  1. the save button did nothing - not even a warning
  2. when trying to build the app I saw the warning below, even though I had chosen the default “blue dice” icon when creating the app; I tried to manually (re-)select an icon, but still the same warning:


In both the save / build app instances if the issue was caused by a non-existent path, the user should be warned that this is the case.
