Any thoughts on this one. 3 days ago, it mowed most of the backyard but had a cutting motor fault and returned to dock. Then it rained. Tonight, I sent it back out to finish the job via yardstick but after about 1 1/2 hours later when it was doing the perimeter it got to an area that I had previously adjusted with yardstick, it stopped and said there was a route calculation error. Interestingly, I drove it about 15 ft into the yard area that it had just cut and attempt to send it back to the dock and got the same error. This is the error from yardstick. **The robot has given up on its route** The machine reported planning fault -12, which the Yarbo app calls WP005, Failed to Calculate Route and stopped. It will not resume on its own. Yarbo app said. Failed to calculate route. Please ensure the map is drawn according to the guide (WP005). ---

You should probably take this talk to the yardstick forum. [Yardstick Forum](https://forum.yardstickhome.com/) WP005 is a error yarbo uses a lot generically for a lot of things. ---

That’s the 2nd time I thought I was on yardstick. I had finally bookmarked it and thought that’s the one I clicked on ☹ ---

I think i resolved it. I had a tow area inside of the backyard. Deleting tow area resolved the problem
