Bug: Response rule concepts don't function

[pivotman319-owo]

Describe the bug

Response rules and their concepts do not function on any NPCs - anything assigned to them will not play correctly. This affects NPCs on all HL2 maps + any mods making use of them.

(The NPC in the above video is supposed to be saying "Was that you knocking? I didn't know we still had a door.")

To Reproduce

1. Run maps d1_trainstation_01, d1_trainstation_02, d1_trainstation_03
2. Try to +use any NPC (the citizens on the train, ration package citizens waiting on line, plaza passers-by and apartments are a good example)
3. Observe them not speaking appropriate response rule concepts

Issue Map

Any map where an NPC has a valid response rules concept assigned to them - all of Half-Life 2 counts here

Expected Behavior

NPCs should be playing their appropriate response rule concepts

Operating System

No response
