so i found a problem with custom card, i made my first custom, and in the files it was named "3000000", and it worked fine in game, but then i went to create another card, that next card didnt worked and never appeared on the deck builder, then i went to the files again and saw that the name now is "3000002", it jumped straitght to 2, but i fixed it by putting "1" on it, now it works.
Thank you, that's exactly the bug. I have the database logic stop searching if there's a break in numbers like that. So it turns out another fix is what caused this issue, the card number would only increase if the folder already existed, hence why it would start at 0, then jump to 2 for the next. Now it properly starts at 1, go ahead and redownload this for the fix.
