There are a few events in the game which just have placeholder text, like when you complete the Sweet girls quest line, or talk to the police guard captain and he outlines a story which will be told. When it says Broken event 3, it might be referring to the third event that is planned. From a coding point of view, this is done, so that the coder can see what should happen even before they have completed the subroutine, that way they can test if the event triggers are firing off when they should rather than for say a character which isn't broken.
