Begin Play Event of HUD-Blueprint not called

Hello there,

I made my own subclass-Blueprint of the standard HUD-Class and tried to fire a simple print with the help of the BeginPlay-Event. For some reason this doesn’t work. I never had this problem before. Do you know what could be causing this?
Thanks in advance.

Double check if YOUR game mode is set in project settings, and then YOUR hud is set in your game mode.
