Like I said, it's no big deal. To me, writing is like making a long road trip from the Netherlands, where I live, to Rome. Very early on, I missed to take a turn at a junction and I noticed only after an hour or so driving. Instead of turning around and going back to that junction, I took a turn left at the next to get back on track. No one would have noticed, unless you looked into the code. Not everything in my story is planned at the beginning, except the destination and a few stops on the way. There are many roads that lead to Rome, and the fun thing about writing is that I can create them myself.
