Idk what you mean by minor update, but let's ignore that for now and focus on how you missed Melissa's sex scenes. My guess is, you focused on being "dom" with her. Back with 0.4, the plan was to use a point system that would basically force you on a single path (locked on one girl) this is not a bad idea if you are focusing on a single game month after month. However, since I am not focusing on a single game now, nor anytime soon... I had to ditch the point system and 0.4.1 allows you to choose the ending for any girl. Melissa, however, only has dom content (She dominates MC) and the plan has now changed to kink-based options, rather than waiting for 6-12 months for content to catch up to the many paths the point system would force me to have. Bottom line: I have had to make a few plot forced decisions in order to fix the entire timeline and make it work for all the girls, with each update. 0.4.5 clearly shows that this method works way better. We got content for Mel, Alice, Aiko, Karishma, Brenda, Vanessa, Leliana, etc. Moving forward, thanks to the support from people like you and hundreds of others who support me, I will be able to create content for Dom/Sub Mel as well. In short. Melissa domming MC is only a patch job that allows me to link everything together. With 0.5 coming with the next update. You will once again have your dom/sub choice with Mel, for good. Getting to see both types of content if you wish, or focusing on your favorite path will not lock you down with a specific girl anymore. You will have an option to proceed with the plot and skipping other possible "adventures" with girls available to choose from, or check them all out and then proceed. Like the optional content for Leliana this update, for example.
And now to end this rant. If you want to see sex with Mel, I'm afraid you have to choose her at the end scene a few updates back and not go after Karishma, or at Brenda's place. Those are split paths that each make you miss content on the other.
