Well, I'm glad I could help but, I think I found either another bug or an issue with my save file where I can't advance to next week, the button is grayed out and refreshing the browser tab doesn't fix it (just like last time just my luck lol). If you'd like I can send you my .json save file to see if it's actually a bug or I got unlucky and the save file broke.
P.s I started a new save after backing up my previous save and the advance to next week button works again seems like my save bit the dust. R.I.P My save file started yesterday and bit dust today. https://drive.google.com/file/d/1VRYOfVDPglDyIRFtAh0pGjI9KoBy20R0/view?usp=shari... here is the link to my save file encase a bug did cause the save to brake.
You found a real one — and this one was my fault, not your save's. When you finish a show and hit "Back to Garage," the game was switching screens but forgetting to clear the show result behind the scenes. A safeguard I'd just added (graying out Advance Week on the results screen so people don't skip a week by accident) was then reading that leftover result and locking the button forever — and a refresh couldn't clear it. The Family Saturday timing threw us both off; the real trigger was a show you'd done earlier.
Good news: it's fixed, and the fix also cleans up already-broken saves automatically — so your backed-up file should load and work again once the new build is up. You don't need to start over. Thanks (genuinely) for the repro steps and the save file offer — "grayed out instantly after X" is exactly the kind of detail that makes these fast to squash. You've got a real knack for bug reports. 🍺
