Your guys' posts are completely useless... First off Brendan, your title suggests that there are faulty dependencies with Ryan's crossings, which really isn't the case. It is kind of obvious to see that they are ATLS, considering they don't work when you never set anything up.
Zelda, (you're what, 12, 13?) what 'map' do you speak of? There was no mention of a 'map' anywhere in this thread, therefor rendering your comment useless and irritating.
TO ANSWER THE OP'S QUESTION:
YES, they require ATLS setup. There are multiple tutorials on how to do this on the forums, and on YouTube.
