Sometimes doesn't find tree right next to you. Othertimes, picks tree thats closer as the bird flies, but a much farther walking distance away. Seems simple to program closest tree, but this program doesn't reliably find the best tree to cut.
It's almost like there is a radius that the bot won't exceed from the position you started in (for cutting, not for banking)
It works though, and it is free, so I can't complain really.
