Enemy Ai stops moving when lighting is introduced

I am creating a 3d horror game and I have an enemy AI that moves to the player when the player is not looking (much like coilheads in lethal) and i was using that to make sure that nothing i did interfered with the movement, as i had to scrap a previous project for the same reason. however, as soon as i added some rect lights to the scene (mostly temporary so i can see) my enemy couldn’t move? I am a new user, so I cannot add any attachments unfortunately. Any clue why this could be happening?
