To be fair it's not being communicated well when its (was) gone, or when it gets added back. Plus there's the mystery as to why it keeps dissappearing. Usually reports of it being gone travel through the grapevine. I've not seen this happen with other commodities. None of this is mentioned in patch notes, even regarding a permanent fix (if it's necessary).
Transparency and supplying more information goes a long way to keeping people informed.
