After maintenance yesterday, Wednesday, august 2nd, my realm will not load correctly and I cannot leave the valley we have built in.

I have looked for fixes and they all say just to close Minecraft and reload and it should be back to normal. I can not leave the valley I am in and most chunks are missing from where I can go, and I can not explore very far before hitting an invisible wall. I have tried changing chunk loading size and nothing fixes it. It seems that anywhere that was changed while I was off, now has a corrupted chunk. I do not own the realm and the host seems fine on his end. We have both tried to leave and rejoin but that gave no result either.
