Hello, Mojang thank you for addressing me and reading this hopefully you can help me,
While I was playing on a world that I have had for around a year or two, I got up to get some food and kit a switch in my room that turned everything on the circuit off with my pc is connected to, thinking it would nothing which normally it does nothing, I kept going and upon returning and relaunching minecraft I looked for the world and it wasn't there at first i was confused but than i looked through the saves in my minecraft folder and it was there but when I launch minecraft it does no appear in the singleplayer worlds, I than dragged it on to my desktop and brought it back in to minecraft's save folder than relaunched and it still wasn't there, after checking my logs the game had said a client/error for a search of the world name which doesn't make sense because it was there in saves but i have a back up but that was in 4/14/19 which is all the way back in a lot of progress i have made and I don't want to redo weeks worth of work and it appears that the backup doesn't work either which is baffling to me because I cannot comprehend the idea yet that my world that I worked so hard on and loved so much had been lost in the game's logs or its internal servers it weird that you would want to Recreate it but I cut the circuit that powers my pc while on minecraft in the ESC menu than with in .50-1 second I had turned the circuit back on in the screenshot i provided you it should be the most recent above Jay survival and on the left the saves file and the missing world Jay I don't really know if this is a bug or the lack or implantation of software. currently i am still baffled by the idea because that world helped my stress level go down, thank you Minecraft.

If you could not recreate it or have thank you anyways.
