Endless runner, floor titles not being created

I am using the endless runner tutorial on this website, https://docs.unrealengine.com/latest/INT/Videos/PLZlv_N0_O1gbY4FN8pZuEPVC9PzQThNn1/3om6yJiYMcg/index.html, I am facing a problem where I can’t get the floor tiles to spawn when the game starts, or is simulated to start. I have followed the video to the tee to make sure i haven’t missed anything and I am also using the same version of the engine that the tutorial is designed for but it just doesn’t work.

Same issue, engine version 4.14.1. No floors being spawned. 2nd movie of the tutorial.

Figured it out - you need to change the “Game mode” to RunGameMode or whatever you renamed it to earlier.
