CHALLENGE mode/Game statistics : Added game statistics for each challenge in CHALLENGE mode.
CHALLENGE mode/electronic challenges : Number of electronic challenges is set per challenge. Electronic challenges are completely disabled in certain matches.
Interface : Tooltips are now shown in in-game menus.
