Im playing 0.13.1 version on Windows 10 PC.
I quit the game accidentally when I walking in underworld and drop into the lava.
After that when i load that saved data, im stucking 'in' the bedrock like the picture i provided and cant move unless jump on the bedrock.
I cant build anything on it and no idea how to get back to the main world.
Hope can getting help for that issue and get back to main world.
