Does anyone know why my secret chest quest step wont complete for chiors catty

I have done the specimen required and played through the entire thing again whilst grabbing the first chest for like the 3rd time and still won't finish the quest

Is that the choir: eternal quest for subsistence. If so, you need to complete an expert run after doing so to get the retrofit

If you're running normal, you're cooked 😦
