Board Game Arena

Hello,

In turn based game https://boardgamearena.com/10/teotihuac ... =490795162, I don't understand why I can't do the action. The game asks me to choose between wood, stone and gold but whatever i choose, the game tell me that the action is not allowed. Do you know why ? And what I can do to play my turn ?

for information, it is unstucked. But I still don't understand what happened
