Game crashes when trying to spawn in a Character Actor

[Michael4Numbers]

Whenever trying to spawn in a Character Actor/Pawn with movement controls in anything but PostBegin, the game crashes with a "Fatal Error!" Message, please see below for the crash log. I was trying to spawn in the Third Person Character Blueprint which works when doing it on "PostBegin" however never afterwards.
