SC 5.03 Seems to fix the crashing issue from the previous version… However; in bmsl_m02, there will be a half way open gate which will TP you into a black void. That is the end of the map. It doesn't trigger the end.

Yes that's true; the default "end" teleports you to a pitch-black cubicle and is pretty broken. It's easy to fix though, just reassign the final trigger_teleport brush as a trigger_once with a env_fade and game_end.

Done, and uploaded a quick fix for the issue. I've added an env_fade to black for other players roaming around the map and added the ending game_text as seen from the original mod. The map will end after 14 seconds once the first person enters that black void. Hope this helps others who play this map!
