Progression bug: Fireflies Quest (act 7)

so, during act 7 I went and killed gruthkul and collected the fireflies in the cave before triggering yeena to actually send me to collect the fire flies. Everything progresses fine, and I eventually manage to complete act 8 with no real issue. but when I came back to the broken bridge and speak with yeena, she still has the fireflies quest text, as if I never finished that quest.
