Stabbing at Shadows Quest Bug (missable quest reward)

[quondoronda]

At the end of Aza's companion quest ("Stabbing at Shadows"), if you choose the first speech option ("Let me handle this"), then suggest Aza should let Dagmar go, then tell Dagmar to tell Aza that the Cult was a lie and then choose the "I changed my mind... [Attack]" option, combat will ensue. Once Dagmar is dead Aza will start dialogue with you again. If you then tell her to disband the cult*, after the dialogue is finished, Dagmar's corpse will have disappeared and you won't be able to loot Aza's advanced mod kit from her. 

The only way to not miss the quest reward is to very quickly loot the corpse before Aza starts dialogue again.

* might also happen if you choose other options, but I haven't tested that.
