Crafting mat drops from treasure maps

[Reap00]

I know I've gotten a Dress Material from a Peisteskin map in the last 2 weeks. I had also gotten a Fireglass Leather about 4-6 weeks ago from a Gliderskin I did on a whim (I normally don't do those).

But I'm also probably not doing as many maps as you do since I tend to stick to what I gather myself on my alts. The items are still there but it's hard to say if SE might have changed the drop rates, or you're just hitting a string of bad RNG.

I also got plenty up till about a week or so ago. That is when I noticed the massive drop off.
