Followed the quest as listed. Went to 2585, -2040 in the Rathe Mountains (aka a pile of froglok remains) Said, 'I wish to recover what is lost.' and nothing happened.
Quality is a job well done (Everquet = Brokenquest) R.
I finished this quest last night. I got to the Froglok Remains right after someone had started their quest so they had despawned. I didn't time them exactly, but it took right around 1 hour to respawn. Hope this helps.
Loc is (+2600, -2050) in Rathe Mountains. Coming from The Feerrott zone, turn right at the first intersection and it's at the first ruins you come to, pretty easy.
