I am a fairly advanced player, so I am familiar with most of the nuances of the game. I am trying to establish a cultural victory, and have leaped out ahead with more tourism than my opponents. The problem right now is with great artists and great writers. For some reason, even though I have open art or writing slots, it does not offer me the option of using the great artist or writer to fill the slot. Instead I either have to use the writer for culture or the artist for a Golden age. I recently had a great musician, but I was able to fill a music spot so I haven't had that issue with a musician yet. Am I missing something? Again I have plenty of open art and writing slots, I'm just not given the option of being able to fill them. Any tips or help would be much appreciated. Thanks so much.
