Why is my BSP invisible?

Hey all. I am trying to build a map in Unreal Engine 4 and for some reason some of my BSP just deliberately disappeared on me.

The strange thing is I have Show > BSP turned on and I see the entire level and to add to that, when I go into wire frame mode it shows the BSP brushes and they are physically there, but they are just invisible when I go to lit and unlit mode. Any ideas on how to fix this? I thought rebuilding geometry would have fixed the issue but it didn’t.

Thanks is advance!

FIXED

If this ever happens to you. Just copy the BSP that is invisible that should fix it and delete the brushes you don’t need.

This just happened to me in 4.16.2 after changing a foliage mesh…

Copy trick did not work, but restarting the editor did.
