Hey guys, So I have been working on a CityRP map for quite some time for Garry's Mod. Everything was fine until one time I compiled the map and there was 0 light being let into my map apart from the skybox that appeared to be lit up. Normal light entities don't even emit light anymore. There is a temporary fix for it (compiling on fast mode in expert) but it casts random black blotches over the map, here are screenshots, help is GREATLY appreciated!
