If I had access to the code, instead of trying to remember/explain the choices that lead to the error, I/and possibbelly other people who use Twine, could simply send the actual passage names and possibly even pinpoint the parts of code that is causing it. Making it easier and faster for you to correct them, so that you could put your emphasis on continuing the story instead of hunting bugs. based on vague descriptions.
I just want to help...and, not to be rude but, based on the amount of code errors I came across, it seems like you could really use it.
But hey, if help is not wanted then that's ok, I won't clutter your comment section futher.
