Well, in the end i removed my plugin solution from before and as -my- final solution 

I modified the assembly and added a null check to the method, throwing the exception , checking for a Brain on the AI before trying to think....

--  Inside "BaseAnimalNPC" class --

public virtual void TryThink()
	{
                 //Added this Check.
		if (this.brain == null || !this.HasBrain)
		{
			return;
		}

		if (this.brain.ShouldServerThink())
		{
			this.brain.DoThink();
		}
	}

I tried all of the above suggestions with no luck.  Finally started deleting the animals one by one to find the cause.
Turned out it was the wild horses.

del assets/rust.ai/agents/horse/horse.prefab
horse.population 0

ridablehorse.population can still be used with no problems.

I did that too. I missed putting it on. A thousand pardons.

Well as i said,  its the trythink method, thats executed on AI Entities without the brain component. 

My Method above is not the perfect solution , but it stops the spam alltogether,

If you wanna try it yourself- here is the assembly from the latest oxide zip , only modified as shown above.

Do these patches now contain a fix?

They contain what was suggested previously by Crushed. This isn't an Oxide issue, we just added a patch to handle the error.

Yes understood, thanks.

Is this patch for
Windows
or
Linux?

I have RUST running on the LINUX server and get error messages immediately after importing it

There are two builds linked, you installed the wrong one.

Thx ☺️

this is on a test server with no other plugins installed

how can i fix this ? 

let me know
grz

Same problem around here.

Less frequently very occasionally this appears on console:

same problem. my solution that worked is to stop my server. backup my world. update umod to the latest last night. start my server again. There seems to be an error with bones something but that only happens early on. now its running fine.

Activating NpcTarget.cs again.

Plugin in perfect condition.

It is not the cause of this error.

Sorry to think it was.
