I have three harvesters on ubuntu and my main node on windows 10. First when I started the harvesters I could see the plots con Last Attempted Proof.
I let the harvesters run all night and now on Last Attempted Proof I only see my local plots passing the filter.
I restarted the harvesters and I see them again.
I checked the logs and all night I can see the : DEBUG → new_signage_point_harvester to peer on my three harvesters.
So im not sure if I was farming or not
