So in a war the other day I experienced a very weird bug. My Nishant's BG went after a slower Nishant's Pet. I even calculated the speeds manually and confirmed that yes, my Nishant's BG should have gone first and that it was not just a visual glitch. I have attached video footage of this bug. @Carlos

Also, i'd like to point out the AI in this clip as well. Why would Nishant's Pet use a single target possession skill on a possession immune monster? There really should be some kind of logic in the AI stating not to use a possession skill directly on a possession-immune monster, as well as something similar for other denial types. The only moves that made any sense in this case were for Nishant's Pet to Blind + Daze one of the targets or try to possess Crissandre.

@Richter5 a Baba Yaga just tried to possess my Jasastur in a fight, so there's still something with the AI. Also in an another fight my Jasastur applied possession and dark immunity and a Nishant's Pet used Soul Piercer (aoe dark possession skill), while it could've easily used blind+daze on my attacker.
Needless to say, I won both fights.

Also in the video, Nishant's Bodyguard was clearly faster ...
