[BNW] Missing Lux

I had 4 Salt pretty early in the game. I traded my 3 extra also pretty early in the game. At some point around turn 140 I lost like 9 happiness and couldn't figure out why. Now I look at my resources and it says I have 2 Salt (clearly I have 4 between my Jakarta and Makassar), and I have exported 2. I never traded my last salt away, nor have I ever been attacked / pillaged to lose access to these resources. Come to think of it I should have 2 silk too and traded my extra there as well.

I did a quick search but couldn't find a related thread sorry if this has been posted before. It is the second time I've noticed it once before the recent patch and today after. I didn't document the prior occurrence.

Okay I have the Salt and Silk listed as +4 happiness, and one salt to trade, but the resource list is still wrong.
