T4 Carnival Radiant Superior Seneschal bugged?

[krj12]

I've used this T4 companion on most of my fire farmers with no issues, she continually applies her buffs for the duration of her summoning.

 

However, I recently got this T4 on my Staff/WP scrapper and tried to summon her on some S/L farms.   She does absolutely nothing, and just stands there.

 

Has something changed recently with the AI, or does she only work for particular archtypes or enemies?  Just seems very odd.

I've noticed something else odd, as well.   Occasionally, the Seneschal will buff me on first summon, but just once.

 

If something was changed for mob AI recently, I think it needs to be reverted.
