In Blast Pit, after defeating the tentacles and going down the ladder, there is a map leak to the right of the ladder (I believe it is only on the map that loads when you are on the ladder, but I could be wrong).
I have an image of the leak attached.
I Did have this same problem, but after moving slightly down the ladder it resolved and vanished.
it only seems to resolve itself because of the “hall of mirrors” effect. I have to turn on the flashlight for it to be clearly visible.
To be fair, it’s not a proper “leak” in source mapping terminology, could even be absent in the editor but only shows up after compile. A leak would produce many more bugs such as fullbright and no VVIS optimizations.
Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
