Hi all, I have a few versions of this Alienbot from in my class that I’m trying to get running. In this particular one, the program is stuck in the no_match_intent function. Typing “exit” as input on one of the alienbot’s questions will stop the program successfully, but otherwise it never proceeds from that function.
