Hey @MvonTzeskagrad and @Klipce; McF4rtson reached out to see if the issue with the scholomance class border was showing up for different people and we're both experiencing it when trying to upload. I would reccommend at the moment just making neutral mockups. Worst comes to worst, we can line up the borders by hand (The legendaries will be fun but it can be done). To that end, try to crank those cards out first, we may need a night or two to line them up if we need to go that route.
Also good luck to everyone who's still going!
EDIT: We fixed it literally five minutes later, shake my head. McF4rtson will probably contact you with next steps.
