Copper Ingot Price has changed

Why and when does the price of Copper Ingots quad-ripple? They are now 48 copper in my game now rather than the 12 copper they started at.

I noticed it after unlocking housing. Not sure when it occurred or if it was patched to be that way. I looked at the patch notes and did not see anything about it.

“* Fixed vendor buy/sell prices on Raw and Refined materials being only ¼ of what they should be”

Which would be fine, if they stopped timegating the refining process.
