AI not improving more than one copy of a luxury

It is turn 141, and Russia's second city has 3 spice tiles, none of which are improved. The Aztecs did slightly better, improving a second citrus tile around turn 125.

Could I see a save of the game? Thanks!

St Petersburg is in the top left. Pachacuti has been a good boy and improved all his incense, Russia, the Aztecs, and I suspect Ethiopia have not. It's hard to keep up wltkd when the AIs want 3:1 lux trades because they aren't improving more than one.

I tried bribing wars to end trade deal assuming they were improved and trading with each other. The numbers didn't change, so I sent my scout to have a closer look...
