Chunk Glitching on Bedrock realms

When you join a realm there's a chance that the chunk your in unloads or glitches out and you fall out of the world. but most of the time you die your stuff is still there. when you re log the chunk is loaded in.

Btw it did not start in 1.8 it is a 1.12 bug but that is not an option for the affect version/s
