Simple camera track player

I openned Third Person example project, made some changes to player blueprint etc. I created new level, added simple scripts and runned it, but the camera don’t want to follow the player. When I open the ThirdPersonExampleMap everything works fine. What I possibly done wrong?

P.S. I hope it’s correct forum.

I had to destroy something in level. After I created new level it works fine. I will now have to create everything again, but fortunately camera moves.
