When a purchase is interrupted, or when the web store is under heavy load, packs with a purchase limit can erroneously appear to be sold out.
This is temporary and will resolve itself within 1-2 hours.
Should the issue persists, please try the following:
- logging out of the web store and logging back in
- use a different browser or trying in an incognito/private tab
If still unresolved after 2 hours and having tried the troubleshooting steps, don't hesitate to submit a ticket.
