When the AI appears stuck in trading, I've tried getting everyone to restart, and that sometimes gets it to continue. (For some reason, one of the players didn't see the trade or the interface never displayed it)
Good updates lately, but still get kicked without being able to view game stats unless in first or last place. If you're in the middle it just kicks you out "No other human players".
When in the middle (2/3 or 2/4,3/4) is when I would like to view the game stats the most. Also the splash just shows dashes for elo on the "You Lose" blurred kick screen, so we have no idea the impact on Player Statistics
Could it be possible that when you could not move the robber, another player still had to discard resources because they had more than 7 cards? Because you have to wait until that is done before you can place the robber.
Maybe you are confusing two things. When a 7 is rolled, every player who has more than 7 resource cards has to discard half of them. If this happens to you it will say on your screen that you were robbed, otherwise it says you were not robbed. Then the player who rolled the 7 will place the robber and possibly steal a card from you, but that is a separate thing and the message does not refer to that.
I was starting to suspect abuse as well, but was able to chat with the last player when this happened. They saw their turn as complete and waiting on the next player, we saw it was still their roll. More common issue for sure and makes me feel a bit better. Wish the devs would get on it though.
