Definitely NOT fixed, hope you are watching firaxis! (or tell me where to tell them)
Austria wanted to trade for gold. I checked to see I had 2, I did, so I hit yes, and get a happiness drop, and mousing over shows no happiness coming from gold.
I don't have the save, but I have an autosave from like 3 turns before it. Will that help?
try replaying the those 3 turns and get the screenshots. shouldnt take very long and it would probably help the mods/devs figure it out.
