How to transfer AI to a new map level?

Hey guys, so I’m really, really new to UE4 (third day), and I created an AI character that can follow me around (third person) and has its own animations. So I downloaded the Soul Cave pack to see how it looks in a different environment.
I was able to get my third person character in, just set default pawn to the player BP, easy stuff… but how do I bring my AI character into the environment? I know it sounds rather daft, all I did was try to drag his BP into the environment. He doesn’t move or respond to my AI controls, but just playing the idle animation.

Thanks!!

Where was the script that controls he ai? Also does the new level have a nav meah
