Error in mb-util

[mrg218]

I am pretty sure that the line of code in mb-util that is now

if os.path.isdir(args[0]) and not os.path.isfile(args[0]):

should be:

if os.path.isdir(args[0]) and not os.path.isfile(args[1]):

Weird that no one has noticed this while using. It now checks if a directory is not a file, while it should check if the second argument is not an existing mbtiles file.

What is the reason that updates of mbtiles file is now allowed?
