I was new to the GUI on lightning and accidentally set my fee rate too low for my funding transfer to clear. So I ended up having to do a roundabout CPFP transfer of additional sats with a high fee to kick it over the finish line and get a miner to pick it up. Not world ending, but it was a pain in the ass and I had to go through quite a learning curve to learn how to do it all. Ultimately it taught me more about how fees work, so I guess it wasn’t bad
