bug: broken symlink crashes.

[Nerdman4U]

Broken symbolic link anywhere at workspace disallows program to find output folder for save.

A system error occurred (ENOENT: no such file or directory, stat 'path/to/broken/file')

[Nerdman4U]

This is because fs.statSync throws an exception.

I will fix this by skipping the exception.
