Pathfinding of tamed Pets in Combat seems broken

1. Title: Pathfinding of tamed Pets in Combat seems broken since Build Number 479 from September 6.
2. Reproduction Rate: 100%
3. Blocker? no
4. Details: The tamed Pet runs in circles and find the attacking Mob only after a while when i'm engaged in combat
5. Steps to Reproduce: Go to a Scene, call your tamed pet and then attack an Mob, when the Mob hits you, your pet tries to reach the Mob, but can't find it so it runs in circles. After some tries, the pet finds an way to the Mob and attacks him. This happens in far or near combat. I've tested it so far in North and South Drachvald Spur.
6. Windows 10, Intel i7, NVidia GTX980ti ...

 

Update:
With Build Number 480 the issue still exist, but sometimes the pathfinding works.

Edit: It's appear in Singleplayer Online mode, i didn't test it yet in Multiplayer Mode.

Edit 2: Tested it in Multiplayer, same issue.

 

I can confirm that.

 

I can confirm too

 

Same result here!
During combat, The pet will sometimes run a hundred feet away then come back to my feet like it reset.

 

Just to add that targeting seem messed up too
My spider was fighting a Elven fighter then right in the middle of the fight she choose to go kill a rabbit who was out of my sight and bring some elves friend
End of the story : I'm dead so she is

 

I can also confirm this issue is present. I tested with a bear patriarch, with the same results.

 

Bug submitted. Thanks!
