[1.2.2] Ukllmswwik has no reaction to killing Slasul

[Snowflake]

I talked with Slasul and agreed to go back and check the dragon, but instead of taking the portal back to the dragon's cave, I just attacked and killed Slasul. The "Temple of Creation" quest says it's completed ("You sided with Ukllmswwik and killed Slasul.") but when going back to talk to the dragon he doesn't show any dialogue option to reflect that. The only options are to attack, tell him you want his treasure (=aggroes) and say goodbye.
