Not at all (no sarcasm), I obviously missed something, like having to click on the waterfall or something.
No, you don't - the game's just dumb. The game was unable to handle its own pathing tools sufficiently well to understand that jumping across the gap (which is a jump that every character can make, even at Str 8) was the correct and intended command, and instead interpreted it as a long path that could very well have run you through any number of hostile situations, or traps, - which it would also have been blind to and triggered, if there had been any.
Having a pathing AI that knows how to interact with the movement tools of the world it exists in is a basic expectation - it's nothing to compliment. Indeed, the fact that this game cannot always do that reliably, and that the pathing AI frequently gets hung up on repeatedly climbing and descending ladders, is something to be criticised.

And yet, at other times, rather than wait, they path through hostile territory in order to 'goo around the long way', which is almost never what any player ever wants them to do.
And yet, at other times still, the characters are granted the ability to jump the distance they couldn't to catch up - ai followers jumping distances that you could not jump, if you were controlling them.
And it is not consistent in this, at all.
No, this is a system that needs a boatload of work, and is not in a praiseworthy position at all.
