Unreal Engine 4.22 Released!

I’m having a weird issue with landscape foliage (placed through the landscape grass tool, not the foliage tool). It’s coming up super bright - seemingly emissive, even though nothing is hooked up to emissive on the material. Looked like this in 4.21. Looks like this now. Notice how in the dark over there it’s still real bright.

It actually looks like some green light is coming from somewhere and affecting this foliage, but I can’t see how that could be. Here it is with sky lighting disabled - the grass should be black (because it’s dark), but it’s green, and the rocks (which are also landscape-grass) are also green (should be brown).
