Player skin changed and items missing upon restarting game

So in my previous report I had all my items go missing after I died, minus one iron pickaxe. I returned to the location where I died with a boat, some sticks, and some porkchops. While investigating the area for my items, I was attacked by a drowned and died again. I closed the game while the "You died" message was still on the screen. I then opened the game again, however when I loaded in my skin had changed from the default Steve skin to the Alex skin, I was sitting in the boat, and all the items I had been carrying were missing, they were not floating in the water above where I died, and they were nowhere to be found in the surrounding area. I'm starting to think the seed (-1403231618) is cursed. The location where all of these events occurred is near the coordinates 404, 73, 852.
