@dimario.banton . . . has this been happening since the 2.3.0 update?
I have “walls” around my home station mat but he walks right up to the walls and tries to push through them, then his battery depletes rather than going back to the home station. This seems to be how I find him every morning and now that I think of it, it has been happening since the most recent update.
You may wish to post your issue here.
