There are certain chunks that always eventually fail to load on my world, it doesn't happen immediately but it will always happen eventually during play. Loading the game up again fixes it but it's still incredibly inconvenient.

It always happens in the exact same place everytime (the area shown in the picture)

The blocks disappear visually but are still actually present in the world, i.e you can still walk over them and they still block your path.

I'm unsure as to what triggers it, but as said, it will always happen during a play session.
