crash saves position but not progress

Sony xperia z5, mcpe 15.3.2 beta

Random crashes, happening anywhere, NOT limited to tunnels. On game crash, player position is saved, but progress is not.

This results in respawning in the last position but without recent progress in the game. Not problematic when not digging, e.g on the surface somewhere, you'll just have to build it again. However when digging, you'll respawn inside blocks, either suffocating or if your lucky and can break blocks you'll be lost somewhere.
