The Advanced Twin Rivers Isle salmon run in the middle of two others (the second from the top twin rivers run in the advanced section) in the list says :
r, l, r, r,l, l, r, r, r, r, l, r, r I've just tried it three times, and there's a typo. It should be
r, l, r, r,r, l, r, r, r, r, l, r, r
Basically, it looks like someone just typed in an "l" instead of an "r". Thought you might wanna fix that.
Anyway, hope that helps.
