As I load up Minecraft, a new logo pops up singing Minecraft hence that meant the snapshot had a new update but the thing that I noticed the most was that as I was trying to play my world that I had previously played with in this snapshot, it and all the other worlds are gone and now my worlds list is cleared. I tried to check if they were in the other versions of Minecraft and as I logged into 1.15.2, the worlds were still there. This I believe is a bug only present in the snapshot 20w14infinite.
