Upon re-entering game after save, character falls from the sky.

Nevermind, found MCPE-38374 has been reopened, though, if it helps, this issue is not happening at the original spawn point.

 

This is after the 1.9.0 update.  I had been mining from the top of a tall mountain down to bedrock.  Saved game. Later that day, entered game again and fell out of the sky onto the top  of the mountain, luckily the mountain was high enough just sustained some damage.  This was probably about 100-150 blocks from my spawn point which I had created a pool on to save me from this issue in 1.8.
