I have a character blueprint with 2 cameras, one is for the actual camera, the second is for the minimap render, but sometimes when i compile the blueprint it will set the minimap camera to the “main” blueprint camera meaning when i try to play the game i am seeing it from the minimap camera’s view instead of the intended one, how do I fix this? 
You can set the active camera with the Toggle Active node. Or for a nicer transition, use Set View Target with Blend.
You can use Set View Target with Blend on your Event Begin Play to set the starting camera for your character.
