Except it is not a problem of it being farmable/craftable or not.
People have been playing this build for months now.
Multiple people.
Yet now, and with no sizable increase in the playerbase to justify it, some of the materials that were once freely available (because it actually was already available, nobody's asking for preferential treatment here) and in apparently more than enough quantity for everyone are now constantly missing.
This is individual-created scarcity, not a "natural" one.
Likely for market manipulation purpose.
How the F is that not a problem?
