Error after robber was rolled...
I was in the middle of the game as the robber was rolled. I had to give up 4 resources. As I clicked all four the window on the right side disappeared but the opponent was still “thinking” (computer ai) i then realized my resources were still there. I clicked on the trade button and it told me to discard 4. So I did. I then had those cards discarded inside the trading menu but all resources were still at the bottom of the main screen while the opponent kept “thinking” (the circle on the bottom right)
