They gave me a Glimmerdust Trove about two weeks ago now, after reading here that you could petition for one to replace the lost quest. Very nice turn around. However I didn't have a trove from an adventure, so my situation was obvious.
I have since got a second from adventuring and I love not having to mine mushrooms. I started out collecting from both troves whenever they were ready, and now I'm maxed out of dust!!! It's amazing - solely because I can get enough sap to do anything with, but that's a different problem
