save_dir doesn't work, but dir works?

[datamonsterr]

I see that you use save_dir in the example, and I read your code, you use both save_dir and dir but the save_dir doesn't work for me and dir works fine. I know that you've just rename dir to save_dir but seem like there's a bug here?

I changed the api to save_dir as it's more explicit but didnt want to break peoples config so left dir in. Both should work.
