WORK AROUND ON NODE REGRAPH OUT OF DATE
After looking through different files and after applying this patch, I still got the same A.I Disable and Node graph out of date problem. Since I can't apply AI_NOREgraph 1 without having the NPC freezes at a certain point,. So I got to thinking and came up with a solution. go under your root folder where the game is and under HL2\maps\graphs open up all the ain files, but before you do set the computer clock to a future date like to 2010 and save each one of them without making changes to it , the fastest way is to use Cntrl+S on each file to save, and in the end all the files should show date modified on 2010 instead of the originall date of 11/16/04. Then go back and change the computer clock to current time, apply this patch to fix the HUD error and Noderegraph and AI problem will never happen again. Make sure you don't edit the cfg file with AI Disable 0 or Ai_noregraph 1 or else the NPC will freeze (during the Black mesa lab) I realized that Node regraph probably have something to do with Steam validation on the Emporio full copy, and the exe file might just to validate the graph date and time with steam with a legit copy and that's why it's causing the Node graph and AI problem. If you have the Full Emporio copy(before proper) or any other version that still experience the Noderegraph problem with this patch, give this solution a try, it should work flawlessly without all the problems.
