I actually think your Candy balance is only updated once a change happens; basically you should be able to use the last update where your balance is featured and just make a new post in the Candy Shop to withdraw/deposit the Candies you want, making you active again.
No harm done, thanks for getting back to me! I forgot to ask earlier, but if there are any other cards in my profile (here) you'd like, let me know, even if they're mostly promos!
I appear to be in the group now. So sorry for the delay, I'll get to all the trades once I message Itzatrap over on Serebii about getting my Candy balance all sorted since I've technically been inactive.
