As of late, I've been experiencing a really annoying issue. I had picked up development of a map due to the porters loss of motivation. I completed the map a while ago and have now found that after compiling and uploading, every person I've had test the map has crashed to their desktop (I've given the map to about 3 people). The map works fine for me with no console errors with the exception of these which have been around before I begun working on the map. According to them, they have had no errors pop up upon crash. I am only running VBSP as of now as a way to rule out any issues with VVIS/VRAD/Packed content as I found this issue when I had the map fully compiled and packed. Been sending the bsp packed into a bz2 archive, tested uncompressed. Used VBCT and the default Hammer compile tool to compile it, both give the same results. Only internal entities (I believe) are func_visclusters, which I removed, compiled and uploaded/tested. Ran the full compile log through interlopers, only to get a 'node without a volume' error. Heres a full compile log from VBCT. Here's the map fully compiled with VBSP, VVIS and VRAD. It is not packed with any custom content however, so prepare for checkers galore. For those interested, the map is vsh_dr_minecraftworld. I've been working on b4 as of late last year after the original porter (Hawke/SaintHawke) decided to hand work over to me.
