i sadly got the same problem, i want to make a sven-coop map with the skins of counterstrike, i have a spawn point (info_player_deathmatch) and a barney my map also has a light with brightness 900. its like a 1 room (kinda like a box) i named it KB100 and i wanted to test it, and it did a lo00ng list of commands and in the end it it wanted to launch HL,
but b4 that happened: Error 5899: Metadata file missing or damaged [-1]
and i know this error is very unknown to this game, but i hope
this lo000ng list will help:
