I posted a question this morning and came back with another problem but my question is gone. Anyway here is my problem.

I need wisp lantern to expand, I need earth wisp to make wisp lantern, but I need rock to make earth wisp. I have no rock so on the forum this morning someone told me where to go in the market to buy it. I did that and now when I try to clear it I get a message saying I can't hold anymore rock but I still can't make earth wisp. What in the world do I do?
