Well that's weird, because I've been doing that all day and I still can't select a maze without it freezing on me. Oh well.

Did you have any troubles getting to the mazes? I choose the maze I want to do it and it stalls, saying what I presume to be "Loading"

I think it's based on how quickly you get done with a maze, not on how many Pokemon you encounter. I've encountered most of the legendary Pokemon only if I got out of the maze fairly quickly. The best way to get the Rainbow Stone is if you enter one of the codes on the first page of this thread when you have at least ten stones of each type. Also, the 'endurance' dungeon is based on a 24 hour cycle; ie if you do it right now, you can't do it right off the bat Tuesday, you have to wait until 24 hours have passed.

So, I'm gonna do this. I choose Poochyena, and eventually found Jolteon, Vaporeon and Umbreon. I friended Jolteon but missed the opportunity for the other two. There's a new maze 'course', which is much bigger than the previous three. You can't refresh with a bottle of water - instead, it appears to use the black metal beans given to you by the various legendary Pokemon you've met. Additionally, you are graded on how far you get into the maze, possibly in meters. There appear to be people in the maze, who possibly refresh your Pokemon in exchange for a bean. You also have the option of not using a stone, and just letting the Pokemon you met go. I'm not sure if you can redo this course after your Pokemon faints, because I can't reselect the maze course. Maybe once you get more beans/Pokemon you can? EDIT: I friended Espeon and have it on my 'team', so it appears you aren't just limited to one Eeveelution. There also appears to be a ranking system of some sort.
