after the shopping trip with Becca and Mei, the MC name reverts back to Frank(orignal name)
I didn't touch that part of the code, so that's on the dev. Have you tried a save from the beginning? That might work. Only suggestion I have.
Let me explain this bug. After the developer released version 1.15, me and some other people noticed this bug and wrote to him, he fixed the bug after a few days and released a fixed version.
Zoey Raven seems to have the wrong version of the rpy script. I recommend to fix it - just add characters [ and ] before and after Frank's name on lines 2034, 2045, 3103, 3202 and 3292 and replace the bad rpy file in walkthrough mod.
Another thing I would like to mention here is the walktrough itself.
1. There are some clear decisions (menus) in the game that lead you to the end of the game, for example. Walkthrough is fine in this case.
2. Other menus are "useless" and do nothing in the game except for a few lines of other text. Walkthrough is lightly useless.
3. But other decisions branch the game. Maybe not much, but there are different cutscenes and it would like a wider explanation of what happens when the player selects a certain menu item. I would consult the original walkthrough for these decisions, as this mod is insufficient for that.
Example: (ver 0.06) If Frank opens the apartment door where he is alone with Beth, he will have sex with her and return home. However, if Beth opens the door, the story changes - Abigail will be masturbating with a dildo in the shower while Frank meets Lilly and Becca and talks to them.
That's my opinion on this walkthrough mod, but want to tell you to keep working on it. I think it's good for players who don't want to see anything but sex in the game.
