Setup: Argrodohm stunned Nhiala, then a fight started without yells or wake echoes.
Here is a log fragment:

(White Aura) Nhiala is sleeping here.
Argrodohm is here.
Argrodohm nods.

-> here tick passed, probably stun affect ended

<962hp 640m 611mv 3 PM>
You can stalk again.

<962hp 640m 662mv 3 PM> stalk Nhiala
You continue to stalk Nhiala.

<962hp 640m 662mv 3 PM> nod
You nod.

<962hp 640m 662mv 3 PM> assass Nhiala
You can't do that to fighting people.

-> so here she's already fighting. Please note that:
1) There was no yell.
2) There was no echo on wake.
I can imagine situation like this without bugs, but it's quite unlikely. Could you please look into it?

<962hp 640m 662mv 3 PM>
Argrodohm gets in one more shot on Nhiala as she flees.
Argrodohm's parting blow devastates Nhiala!
Nhiala has fled!

I have no idea how combat started. Don't even know where to begin looking.
