game #139989 on oregon
I don't think Tower was scored at all. At least, it didn't show up in the after-game report, and the after-game report matched the ending VP even though the game ended on piles and the points for the last pile wouldn't be known until after the game ended. Unless Tower just doesn't score for base card supply piles, since the last pile out was estates, I had bought 7 of the estates, and the VP counter said that we'd be tied if he bought the last one. Since there's no way the VP tracker would know the estates would run out, it must simply be the case that the Tower points were not applied. I think we split the other two piles evenly, put I exited from the game before realizing that the final screen was the only place I could see what all happened that game.
Tower: "When scoring, 1VP per non-Victory card you have from an empty Supply pile."
