Blueprint Debugging

Is there a good tutorial on blueprint debugging? Looking for a way to step through each node / process of a certain blueprint to find out why something is (not) occurring.

Well, if you add a breakpoint to a node, and then play in editor, when it reaches the breakpoint, you can step to the next node, or skip to the next frame, with the buttons at the top of the blueprint editor (or pressing F10 to step).
There’s also a StackTrace node that supposedly prints a stack trace of how the node was reached to the log, but I’ve not used that. Not sure of any tutorials, but the breakpoint/stepping is fairly intuitive, and makes it easy to debug along iwth using things like print string or draw debug line etc. when needed
