Subject: [PATCH] Do not change rooms if scene failed to load

Sometimes a following room fails to load (e.g., #582) and instead of fading to black (as no scene is active) when trying to enter that next room, the player will stay in the old room and an error is logged (as throwing one crashes the game).
