I was doing quests and then I found what I assumed to be a bot attacking my Ice Wall for no reason in a grinding spot. I started whispering to him just o make sure. My Steam screencap of the incident. http://steamcommunity.com/sharedfiles/filedetails/?id=659427001
I was also in another larger grinding area of Tenet Garden that had random bots log in and out constantly when mobs appeared and they would disappear then the mobs were cleared out. Then fresh new bots would appear before they would re-spawn. I have no screenshot of this. But I was in a single digit channel from what I remember. I think 3 or 6.
