I just gave myself vertigo. A pleasant kind of vertigo, like the world has been lifted off my shoulders. I'll explain:
Yesterday I saw to my dismay, that I had made my entire map two - two - units too short on every level - that every set01 piece was sticking 2 units into the ceiling. That's basically 402 brushes that needs to be realigned (minus the ground floor brushes).
I knew enough about selections to do all of that in a very tense five minutes, and it compiled without leaks. (Thank you so much, Dark Radiant devs, for making an editor with such care for precision that you can align hundreds of brushes perfectly at once (which is not something I can say for Valve's Hammer editor, which has some serious issues on that front, which actually made me just quit it in disgust).) However, the result is that the entire level has now been stretched a barely noticable 2 units, and it will take some getting used to psychologically.
