I started mapping for KF recently and ran into some issues. I am working on a map, all is fine and dandy.... then POW! I am trying to make a connecting corridor for two rooms and the vertex manipulator suddenly won't work. I am also getting the brush jumping around when i try to align it to the grid. On top of all that, just making a simple staircase is proving a real challenge. It wants to create a brush instead of a solid, and creates the solid entity in it's MIRROR location. All of these are things I've done before, with little to no trouble, when I first started the map. Can anyone help, or is the only solution to scrap and start over?
