Your file has a rules error.

The building co-operation bonus and the end game scoring are both conducted in score order, not reverse score order.

Also, you mention that you block one build spot for 3 players, you might as well point out that you block only 1 spot for 3 or 2 player games. People my deduce that if you block one for a 3 player, then you would block 2 for a 2 player (since that would mean there was one less space then the number of players in all scenarios), which is not correct.

I don't have the rules in front of me, but I swore the player in the lead got their point first. Huh

...

I don't believe blocking a space for the 2 player makes any difference at all does it? Or wait, there is that one silly "place upriver" card.

Hrmph. Well if I find my source file I'll see about updating this.

No you are right, it is in the person in the lead that scores first. Your aide says "reverse score order" for that, which would mean the person in last place would score first.

My point with the 2 player thing is that someone may read that and think "well how many do I block for 2 players, guess I'll block 2 of them so that only 1 player can go there, since it looks like you should have one less then the number of players there" It was just a minor suggestion.

I really will try to get this updated in the next couple days.

Are you still planning to update this? It's an excellent player aid, but it really does need the changes suggested by Adam to be implemented in order to be accurate and useful.

Awarding end game points is also in score order.

Both the German and RGG manual mention that end game scoring is done in reverse player order (player 4, then 3, ...)
