Strange Title Screen Bug (sweet berry bush)

I Died In Hardcore Mode to a sweet berry bush and whenever i load the world and select delete world it takes me back to the main menu where the background is silver when i try to go back into the hardcore world (whilst the background is silver) it leads to a black screen and the game stops loading the world relaunching the game makes the background go back to normal however upon loading the hardcore world and pressing delete world it goes back to silver and then trying to load the world after it is silver results in a black screen

What I expected to happen was...:
**

After Death The Title Screen Would Have The Normal Minecraft Background and i could go into the hardcore world and leave without a black screen 

What actually happened was...:
A Strange Silver Background Appeared Instead and attempting to revisit the world after this accurence resulted in a black screen (most likely a game crash as minecraft has not responded in the last 12 minutes.) the game is also having trouble closing and it is still open.

Steps to Reproduce:
1. Hardcore World No Cheats Structures On
2. Die To A Sweet Berry Bush (i was at half a heart and at around 4-5 hunger
3. upon death select delete world and it should take you to a strange silver screen
