AI and Trading Bug
I have just played a trade goods monopoly card for cloth with Seafarers and Knights in the scenario The 4 Islands. I was supposed to receive a cloth card from the AI. Since then I have had a display that I have -1 cloth city expansion card and since then I have no longer been able to trade, nothing to expand, only to roll the dice.
Despite multiple reloads, restarting the game no change. Apart from the fact that the AI only attacks the weaker player, as it has for more than 4 years.
