Only thing I've run across are marshes that probably weren't intended to be marshes. Is that a good thing? Or not?
That means the water table was either too high, or the color scheme for the water layout is off by height,
or that the land mass has been lowered a few blocks too low. Well at least that is what it use to mean,
most of those settings have been removed and according to a note in biomes, have been set to dynamically
render now. I saw it on one of these renders, and it was blank in areas, so I hit the edge of the water and it
fixed itself.
Looks like some of the water and ground didn't render in properly, I would suggest just shooting the ground next to the void.
That's what I did at first and it worked, then I just clicked check stability and that worked, but you have to be close
to the gap.
I turned water from low to high then back to low, turned off distant pois then back on mine is set at 2000, walked,
ran, flew to see if it was a delayed issue. Dm, and basic player.
Changed from center forest to center waste, maxed forest and rivers, returned to default.

The only thing I can say is after, 11 game starts and 11 different maps I am not that curious anymore.
Almost forgot I repainted the snake river, to see if that would possibly help, nope same thing.
