I have a pipe that fetches a feed, parses it, and displays an image from each item in the feed. I made a clone of that pipe and modified the RSS feed, which comes from the same source and is identical except for the content (XML structure is the same). However, I get 2 different results. The first feed, I get an image. The second feed, I do not.
Again, I've looked at the raw XML the structure is the same. I have no idea why one pipe would fetch the image correctly, but not the other.
It's more likely that the pipe has been changed after having been published. In that circumstance the original pipe will work according to the most recent changes. But any clone will be a clone of the pipe at the time that the pipe was published.
