Okey dokey, i'm working on a HER-UGE mapping project, and i'd gotten to the first stage I wanted to be at before I tested it. So I try to compile, and everything goes fine up until the end of the .bsp generation. Here's the part of the log:

BSP generation successful, writing portal file 'C:ts_rooftops.prt'
Error: ReadSurfs (line 1): 228 > g_numplanes

--- END hlbsp ---

And from there, it didn't work, gave me the 'your map contains an error that must be fixed' thing and I don't know what this error is, or how to fix it. PLEASE someone help me, I want to finish this map, as it is going to ROCK! :(
