when i first started mapping, i spent like 8 million hours laying out this map. it compiled fine in vhe, and using zoner's tools, ran in counter-strike after compiling. but, i noticed when i would try to run it starting from counter-strike and not from vhe, it wouldn't load and said something like "exec not found" and would never load.
after searching laboriously to find some weird error like a bad brush or entity or leak or some obscure problem, i finally decided that it was just corrupted somehow and that it just wouldn't work. so i deleted the map and started from scratch. only after another 8 million hours of redoing it, i realized the problem wasn't the map, but it's filename:
"my map.rmf" instead of what it should have been: "my_map.rmf"
after figuring this out, that something as small as one underscore/ nonspace character was stopping my map from loading, i was partially relived that i found the mistake, but mostly stupifed at all the time i wasted shiting around looking for another reason why it wasn't working.
has anyone else done this? i hope not, but i decided to post just in-case
somebody just starting was making the same mistake.
yes, i know i am a retard. hope this helps someone.
