Thank you for the reply!
I guess you’re not using any kind of Version Control System (like Git) for development? If you did, then making a small patch for an earlier version wouldn’t be a problem.
If not, then as a developer to developer I can recommend you to check it out. Not for our sake and not to patch Season 1, but to be able to secure your development process and to be completely sure that you’re not going to lose your work in case of some kind of hardware failure or some another mistake. It can also help to track bugs if you know when they were introduced. And a bunch of other benefits.
