Targeting delay?

[Mickey4000]

I have noticed with the new update that there is a slight targeting delay, once one creature is killed it delays attacking the next for around 5 seconds, continuing walker in the mean time. Is this something anyone else is experiencing. If so how can i get it to attack instantly?

Same problem here. Let me know if there is any fix to this

Can you guys post some screenshots of when it's not attacking with diagnostic information turned on? (Visuals->dgnstcs)
