My Ender Backpack lost its stuff. Where did it go?

There can be several reasons for this. These are the main two:

1. You loaded into a different SM server. Each server saves your data exclusively. To get to a previous server, go into the “Survival Mode Book” in your hotbar, then find and click the “SM Selector” button. The “SM Selector” menu will allow you to choose from an active SM server that’s in rotation, choose from recent servers you have been in, or choose a suggested server.
2. The servers reset. Our servers reset twice a month. Server resets the map and wipes all player data from all inventories, including Ender Backpack inventory.
