welp, black mesa pooped itself in Questionable Ethics. AI disabled itself, guessing due to node graph fuckery, realised I had a bunch of mods that are no longer compatible loaded, so unsubscribed from them now that they're all no longer needed, and tried to reload my save and the AI works!... but the lazer that you need to activate to exit that chapter ... worked?? but the terminals were missing. aaand then it crashes upon leaving the chapter in any direction. D:

heck. time to restart. :<
