I have noticed a little bug relative to cleric bots. I was playing my ranger and wanted to quickly get past a few mobs. I invised myself and my cleric bot. We arrived at my destination in the basement of unrest. While there I started killing mobs and noticed that he kept on healing while staying invisible. At first, this would seem like a benefit, but an item dropped and I wanted to use the #bot giveitem command. Though the bot was targeted it told me that I had to target my bot. Additionally, I dinged while down there, and it would not let me used the #bot update command. I did have see invis ability, so I am not sure what the deal was.
I just thought I would share what I saw. I hope this helps.
