[Bug] Look rotation viewing vector is zero

[tgraupmannParticipant]

It looks as if the Move action is missing a != Vector3.zero check. Probably when the Move action faces toward the target, an invalid Vector3 is not checked before calling Quaternion:LookRotation.

Logging this error repeatedly impacts performance. See the stacktrace below.

Interesting. Started getting these now too as I merge my simple BT’s. Thought this was addressed back in 2013?

Started happening to me too. Might be related to upgrades in the Unity API post 5.2?
