Your plan page shows the credits you actually have

If you opened Billing → Plan since the move to credits, it told you that you had 0 decks available — one click away from a buy button. You didn't. The line was still reading the old deck counter, which was converted into credits and emptied when everything moved onto one wallet. Nothing had been spent; only the reading was wrong.

The plan page now shows your credit balance, and — when your plan includes credits — how much of it came with the plan and how much you bought. The two are shown apart because they behave differently: plan credits roll over up to a cap, purchased credits never expire and can be refunded while unspent.

Two related fixes:

• The price on the plan card is the one you pay. The renewal line now reads the plan you actually bought. It could show a retired price instead; if your account was set up by us rather than bought through checkout, no charge is shown at all, because none will be made.
• A heads-up before you run dry. When your balance can no longer cover a full deck, the overview now says so at the top, with a link to top up. It stays quiet while you can still make one.

No credits were lost and no balance needs correcting.
