I figured it was something like that (and of course, it's not a big deal). :)
Nah, there is no way RPG Maker could generate something like that automatically, I added all the various options little by little (sometimes after a player's suggestion). A good chunk of the options in the travel sphere are meant to help me quick test parts of the game and the rest is to let players cheat a bit, if they want to. It's a bit messy, but at least it has the most important options.
Re-organizing the travel sphere wouldn't be a bad idea, it's just tough to find the time, since it's not essential.
