I only took the easiest example under which circumstances you could end up running into a wall.
If you prefer more complicated reasons when and why even you would run or jump against something ... uhm, give me a week or so, to find one... But that doesn't matter. If developers want to fix this bug, they need a reliable way to reproduce it. They don't need an IC reason to behave so.
I'm only looking from the technical side of this issue. You instead seem to prefer the roleplaying side. But bugs are technical issues. Solving them is a question of "how do they occur due to the code", not "why would anyone do it".
Furthermore, that I happily took the bartender job a year ago, doesn't mean that I still do. But there are still more reasons to jump. And if it is only to climb e.g. the wide ladders of the watch towers. Or to jump onto a pile of boxes or onto a plateau and shout. Or to pass the pipes in the sewers. Or to get to the backside half of the Akkaio warehouse. Or just to have fun.
Do you have fun too? Do you sometimes jump? - Probably yes, according to the fact that you can climb the plaza wall near Harnquist. Are you just afraid that fixing this bug would disable you climbing it?
Sorry...
It may sound more offensive than I mean it.

P.S.: Exploring the ranges ... isn't it just human? Isn't it the spirit of exploring? I am software developer, I love exploring my ranges of abilities. Also I love to explore the ranges of a game. If you don't explore, you don't find bugs to be fixed ... before they are needed when old ranges get removed one day, by new features.
The older bugs are, the harder they are to fix. Better discover them early.
