Just happened to look at screen while HB was running an AV. My bot was standing in place mounting and dismounting over and over it appeared to just be continually mashing the mount key. There were also 3 other players in range of me [pretty much in a line] doing the same thing. I manually ran the bot from outside of our spawn and while running I saw two more doing the same thing. I just turned AV off my random battleground rotation but I'm sure there are plenty of other people having the problem if I was 1 of 5 that I just happened to see in this AV.
