PIE crashes on levels with pre-placed buildings unless game state is a subclass of `AFGGameState`

[Th3Fanbus]

Try to play in editor in ExampleLevel, expect a crash on this line:

SatisfactoryModLoader/Source/FactoryGame/Private/Buildables/FGBuildable.cpp

Line 324 in 476dd90

AFGGameState* gameState = CastChecked<AFGGameState>( GetWorld()->GetGameState() );

Suggested workaround: modding edit that makes the cast not checked, and adds checks where gameState gets used.

Problem with using a subclass of AFGGameState is that you need to implement the full thing, whereas AGameStateBase works fine for testing a few things in the editor (e.g. Wwise spatialisation).
