AI is trading ressources it doesn't own
Just played a "Schatzinsel" 4 player game, 2 human players, 2 AI players (Candamir-Veteran and Jean-Veteran).
I played a monopoly card, asking for all lumber, but there wasn't any. Next move is the other human player rolling dice, resulting in both ai players receiving 1 (!) lumber each and then the other human player traded 1 grain for 2 (?) lumber with Candamir.
