Hi!

I'm trying to create a new exterior worldspace but I'm having some trouble with the terrain.

As I move the brush around to change the terrain the brush occasionally disappears and I haven't found any way of bringing it back.

I usually just try to reload the cell and sometimes I get lucky and it works again but most of the time it doesn't.

A second problem that I have encountered is that large objects (like mountains) placed in my exterior cell can sometimes turn invisible as I move the camera around.

I don't know if this is related to a common bug in the ck or something else but any help would be highly appreciated.
