The Hidden Forest

What am I supposed to do with this? And before anyone says "turn it in", note that the Adventure Token npc won't take it, and the vendor box won't buy it.

From Sol to tower? Can be sold back to ldon point vendors

You did see what I said above, right?

Nope, I read it half asleep. It is supposed to be vendorable

I made another post to point out that the vendor boxes are not buying the regular aug drops either.
