"Replay" folder not automatically created, but crashes instead [BUG] [NF-PLAYER]

[Nepster]

The new-formats experimental player does not create a "Replay" folder when trying to (automatically) save a replay, if no such directory is present in the player's folder. Instead the game crashes and has to be closed brutally, because it no longer reacts to any input.

This should be fixed in the new exp build. Let me know if it happens again.
