While there currently is no way to view your complete inventory of Collectibles, any Collectibles currently not needed for any Collection will remain safe in your account. Once you have a Collection that requires them, they will appear as you left them.

Additionally, keep in mind that your Collectibles inventory is global. This means that a Collectible that is required in two Collections will show in both at the same time with the number you have in your inventory. If one of the Collections is finished and claimed, the Collectibles will be deducted from both Collections.

If you lost progress in a Limited Collection without using the Collectibles, please be sure to try out some basic troubleshooting. If this does not help, feel free to reach out to Support, making sure to include your Support Key and a screenshot.
