I have a playerclip that is rounded around some brushwork, going up to the skybox. For some reason if you jump against it at some angles and hold forward against it, you stall out mid air. It is absolutely 100% straight up and down. It does seem like the corners seem to cause the most problems. A video of the problem: http://www.youtube.com/watch?v=codUuex0sGY This is the brush in question: Any ideas what is causing this? I really don't want a bug on the map like this. If all else fails I will probably put a trigger_push away from it, but I'd really like a cleaner fix than that.
