Yeah, the Wordlebot told me my third guess was "lucky" and told me a different word, which would only have revealed 2 greens would have been "more efficient." So I solved it in four and the Wordlebot crashed out but is telling me a lesser word would have been a better guess?
Fuck the Wordlebot. It exists to annoy me. I'm glad I'm old and likely won't live to see the machines take over the world.
