Gross! LOL!

Well, I think it boils down to the fact that the colour key cutout colour is fractionally different to the colour used to draw the rivers.

The Color Key is set to be colour 95 - the end of the second blue line, but the colour of the river drawn in the map is actually colour number 79, which is the colour at the end of the third blue line.

To cure it, either edit the Color Key to be the same colour as the river (colour number 79), or change all the rivers to be the colour of the Color Key cutout colour (95).

I'm not sure how this has come about, or why no one has noticed it before, but if it is wrong in the template I will let Ralf know.

I think the video you remember might be this one?

Awesome, because you managed to finish it, but good maps as well :)

Love the mouse!
