Hey Pouakai,
I tried the wonders mods listed on the Steam Workshop as you suggested for G&K, though I downloaded the files from the CivFanatics database pages linked to on the first post of this thread. Most of them still didn't work - don't know if you haven't fixed the <culture>tags on these, or if there are still bugs. Am I just downloading these from the wrong location. Don't need a big response, I'm happy with the game thats developing with those that do work - this is mostly for your information. The first list is wonders that WORKED, the rest were loaded but didn't appear in game - there doesn't appear to be any issues with with expanded files.
Working: Stone Town, Shwedago Paya
Not Working: Torre d'Oro, Golden Pav, Teotihuacan, Temple of Heaven, Taipei101, Pearl Tower, Malwiya, Kronborg, Karnak, Grand Canal, Florence, Broadway
