Data not saved properly after a crash

I was using a shulker box on my world, then i mined it and got it in my inventory, and the game crashed about 30 second later (i have no idea why but it crashes every 5h or so)

When i re-opened the game, i was in the place i was when using the shulker box (even though i had moved before the game crashed) but the shulker box was not there (normal since i mined it), but it was not into my inventory either, and the items i putted in the shulker box where in my inventory again

so i came to the conclusion the game saved the world but not my inventory, therefore making my shulker box disapear (kinda sucks because it was the one i use to store diamonds )

Hope this get fixed as it can make you lose a lot of items if you lose a shulker box via this bug
