Anyone who has quest for DoT in Neph chain simply needs to go to Canyon and tap on the ciklotor. So you won't have any issues even if you're still at this quest.

I had the quest for DoT, its gone. No other quest for Neph showing up. No ciklotor in Canyon. Last time I saw it was the last Breath of Abyss in which I would have had to click the thing to sacrifice essences. Have some other advice or assistance?
