World got auto-deleted when saved and quit

So I opened my survival world with an unofficial texture pack to find the character wearing the default Steve Skin, so I presseded to save and quite. The screen was normal, but once it was all complete I was greeted with a world tab that deculuded my survival world. I tried going to the main screen and back, and quit and join (I realized my Ethernet cable was down and I had not a wifi connection, so I plugged the cable in before I joined); However, nothing worked*(my skin was back, but as I went to check the storage I did not find my world nor the texture pack I got from the internet).* I did restart the device although that did not change the situation. This bug costed me my most advanced gamemode-S world; Thereby, I would like it to be fixed as soon as possible; And for, players to be more careful before they press on their worlds.
