I got this error when a summoned turtle uses taunt in current (revision 1496) svn:
turtle 48137 dumb ai talents can use Taunt T_TAUNT
dumb ai uses T_TAUNT
[LOG] Turtle uses Taunt.
USING table: 0x27b5e40 Taunt

When it happens the turtle goes in a taunting frenzy. And seems that every taunt wast a turn. The game becomes sluggish and I cannot move.
I got shocked to death when I summoned a turtle in my fight with the elementals in Bree...

Re: Infinite taunting - SVN
Like I mentioned in the Radiant Fear thread, I think this is a bug that my target refactor has introduced and I am looking into it. 

<DarkGod> lets say it's intended
Re: Infinite taunting - SVN
Ok, this should be fixed but won't be committed into the SVN until DG looks over it.
