Bit of a confusing problem. As you may know my maps is rather large, and I'm used to various "too many objects" errors on loading it in Worldcraft and things like trees not showing up in the editor, but showing up fine in the compiled map.
Now I'm having brushwork disappear (in all views), again it shows up when the map compiles. Individual buildings are worked on in smaller test maps and then copied over, but the problem comes when positioning them correctly if not all the brushes are present!
Is there a solution or am I just overloading some older software?
