Interesting... The next sequence is supposed to trigger when you enter the grassy area just in front of the jetty. Thanks for checking it out regardless.
I won't update the bug until the jams over but it happens if you activate the radio more than once. So on that third gameplay section all will work as indented if you interact with the radio the one time. (I've not set a trigger box location, instead moved it on the interaction with the radio)
