Game hard crashes whenever tick function is run

Hello, I've created an attribute called hero_of_village that's applied to all players and has no code associated with it. However, when I generate a new world, the game full crashes. The errors seem to complain about the attribute, but I'm unsure what I did wrong or if it's a bug.
