My bejeweled backpack deletes everything inside when I teleport or go to and from the Nether (haven't been to the End yet in this pack). I'm on All of Fabric 3 2.0.5

Having trouble reproducing this. Was there anything I missed in that clip? Is AOF3 on 1.3.0 for Inmis?

I think it is using /tp command. I had this same issue, and thought it was gamemode issue(as I was going through creative, spectator, and survival). Also, Xaeros Minimap uses teleport.

Feel free to re-open this issue if you encounter it again.
