Glitch when u craft

Okay I was playing minecraft realms and everything was fine until I was crafting a cake so I grab all materials that I need and I click the cake to craft it. And it went to my inventory then I open my inventory theres was nothing! So I created again and it did it again restart the game and still the same and killed myself in minecraft and I build it again and nothing. And I had a dog and he was just sitting there and the next day I play he disappeared outta no where please fix.
