I haven’t found a place that doesn’t suffer from this. Because of how janky it is I try to stay near my base, but all of the defari camps around the summoning place will get to a point where none of the collidable parts will load. I have also seen some of the southern dogs of the desert camps do this as well.

Player structures seem to load fine from what I’ve seen, this seems to be specific to developer placed objects. As far as the world not loading, I have been able to run up to the “edge of the world”, and if you step onto it you go into a falling animation, but your position doesn’t change and you are able to walk back to the loaded section.
