Is it possible to change navigation for an AI character during gameplay?

As near as I can tell, following lines should clear up most, if not all, of those errors:

#include "../Sockets/Public/SocketSubsystem.h"
#include "../Networking/Public/Interfaces/IPv4/IPv4Address.h"
#include "../Sockets/Public/IPAddress.h"

I am not too sure how those files related to EngineKismetLibraryClasses.h, though.
