Anyone else get frustrated by people who take good placements or place on a trading post to disrupt someone else's placements but then quit a few turns into the game when people start placing the robber on the good spots they picked? I can't count how many times I thought I'd lose only to end up coming back to win in the end. Probably wouldn't be as big of a deal if the AI was better or having the AI come into the game didn't bug it up as much.
