Hello,
I’m really enjoying this mod but faced a gamebreaking bug (for me) that doesn’t allow me to continue this amazing game. :[
When I kill the helicopter with the rocket launcher (in that cliff level) the game completely crashes. Any idea what I can do about this?
using dual e6600 at 3ghz
ATI 6670 1gb
3 gb ram
Many thanks in advance! 
attached mdmp file as instructed

I’m having the same problem. It crashes every single time, regardless of how I change my settings. Please help!
It’s really irritating because I have had a flawless experience so far. Then all of a sudden I simply can’t continue the story ! 
Not to mention that bastard helicopter is hard to kill in the first place lol !
Just a quick update.
I managed to stop the crash from happening by going to taskbar and setting hl2.exe priority to “high” instead of “normal”. No idea if that was a coincidence or I was just lucky. Hopefully somebody would know.
