I am seeing the same issue as ladygamer at level 37
Here is what is happening in more detail
He kills a mob in a spot, then stops and I am guessing thinks he is killing another. I am attaching 2 logs showing some of what I was seeing.
First I put logging in Debugging and this was coming up in the logs.
[10:20:00.355 N] Take Guardian Ambusher as best target.
[10:20:01.923 D] Invalid Session
[10:20:01.952 N] Take Guardian Ambusher as best target.
[10:20:47.235 D] Invalid Session
[10:21:02.834 N] Take Guardian Ambusher as best target.
If I would just move him a little to another mob he would continue to move around until he basically got back to that spot. While in that spot he only killed what agroed him.
I stopped and reloaded the bot to see if it was something with the session and this time put logging in Verbose, and this is what I seen in logs when he was doing the same thing.
[10:24:10.973 N] Take Guardian Ambusher as best target.
[10:24:11.467 N] Killing Guardian Ambusher at 3 yards with 2564 health.
[10:24:11.467 D] Executing chat command: 'petattack'
But he never did this, he was just standing there, I am not sure there was even a mob within 3 yards as it was saying, I moved him a little to get agro of the closest mob and he killed it and started moving again.
This is the hotspot area this appears to happen in for me.
[10:26:28.763 N] <Hotspot X="5655.077" Y="1008.723" Z="2489.529" />
If i move him slightly out of there to the next batch of mobs he continues on again until he gets back to that spot
I see a hotspot close to that point, that I may try to remove to have him avoid that area a little.
