I did that as well but it copied the duplicate brushes over to the new map. I think my editor is possessed! It does some weird things like hide brush work and actors for no reason then they show up a week later~][FGS][Nobody~ wrote:A rebuild from scratch might help too.
e.g. copy all actors brushes, select new map, paste it and rebuild.
That was also the way, I fixed most of the duplicative brushes on your trial map, Chees.

Ah well map is nearly done just 300 kb of detail to add and ditch the DX Studio sign and package.
