Lightmass Bug Leaving Small Black Gaps On Terrain

This happens even if I don’t use a lightmass volume. it is seriously annoying as I don’t want to use sculpted terrain, I want realistic terrain from a professional terrain generator. This does not happen in Unity which I just transitioned from and now I’m starting to wonder if that was a good idea seeing as how I can’t find a solution for this. I’ve only seen a few people mention this problem but there has to be a ton having the problem since it seems to be right out of the box when trying to use a heightmap for your terrain. I honestly cannot even use this engine if this is going to be the norm. But I know it’s not happening to everyone becuase I’ve seen people do tutorials on Youtube that I have followed exactly and I still get these same exact hole like artifacts scattered randomly all over the terrain. It makes no sense at all…
