Level editor forest brush bug

I was working with the forest brush and I had to go do something so I saved and closed editor but when I came back I ran into a issue, Any chunk that has not had a forest item in it let's me add forest items but they can only be seen from a far distance.
Is this some sort of performance optimization bugging out? If you delete the forest add make new one it is fixed but you have to remake forest and it just happens again so until this is fixed I can't use forest brush.

 

Can confirm that something similar is happening to me. Every one and a while while placing trees, the trees will be there but not be visible. You can select them, rotate them and everything, just not SEE them. I found that if you hide the forest in the object editor and un-hide it, it will render in the trees that were previously invisible. It's a very odd bug, I'm glad I'm not he only one having it.

 

Experiencing the same issue as well. I deleted my forest object and created a new one but have yet to see if it holds. I had other issues with trees painting sideways, upside down you name it. Was happening on two different mod maps too. Bizarre.

I posted pics of my issues a couple weeks ago and when I get home will post them here.
In the screen I was unable to paint in the area where the manually placed trees are. Vast square areas
would not paint or the LOD's were all messed up.

 

I am having this issue on what appears to be every map. I’m thinking this started after one or two updates ago because I painted a very thick forest on a map with no problems like this.

When I pan back a long ways I first see shadows of the invisible trees, then the trees themselves appear. Zooming back in and they disappear again. It seems fairly random but in large chunks of the map.

My workaround has been to save the level (each time this happens) then reopen it. Then all the ‘invisible’ trees are visible.

 

I recorded a clip of what's happening just in case the devs or other people still don't know what we're talking about.
