  Changed paths:
    M src/game_initialization/configure_engine.hpp

  Log Message:
  -----------
  fix ub when starting a mp game 

the code in mp_create_game calls config_engine_->game_name_default where config_engine_ is nullptr which crashes if the compiler does debug checks on whether config_engine_ is not nullptr before game_name_default() is called.
