When logging in to a multiplayer server shared with friends, and this is after the update/change happened where chests are reskinned into present boxes, we:

• appeared back in spawn point, when that's not where we were when we last logged out
• lost all our levels, and our inventory items including our worn armor

We didn't die prior to logging out, and we've tried logging out and back in, to no success.

EDIT: added a screenshot of the point we were spawned on

Although, this wasn't taken exactly in that moment- I didn't think of taking a screenshot like this purpose back then, we just logged in, the above happened, and we promptly logged out with the assumption it would go back to how it was after the christmas change isn't there anymore
