Hi Warrior,
It can be very frustrating if your precious items disappeared from one day to the other. However, pretty often such cases can be caused by server synchronisation issues. Therefore, we recommend you to proceed with the following steps as they helped for various players to solve similar issues.

1. Restart your App
2. Reinstall your App
3. Clear the Cache of your App/ repair the files
4. Reset your internet connection

But if the items are still not appearing again afterwards then contact our support via the game with the following information:

1. Your UID + WorldID
2. Date the issue happened
3. Exact item + amount that disappeared
4. Also state how many item of it you had before

These given details can help our support workers to trace the item accordingly in your game protocols.

All the very best,
Your DECA Support
