Casting to game instance always fails when packaging the game

Double massive thank you! My first level Blueprint casts to the game mode to set some variables, then spawns a camera and a bunch of other stuff, game would load, wrong camera, no HUD, figured out casting to my game mode was failing with a print string, found this thread, issue fixed, oh man, you are a life saver. Any word on this getting fixed? I had the same issue with 4.17
