Not sure if these are the "glitches" referred to but yes YYB received quite an update today and there are a host of terrible things involved.
- Fullscreen mode is now optional, allowing you to play the game in a smaller window as in previous years.
- Switched scoreboards at the end of the game for those playing right to left are now fixed to show the correct teams.
- Goalies can once again be controlled by pressing the 'V' key.
- Pressing shift once again forces your players back into their starting positions. Note: Some users are unable to get this to work at all. Others report it will also force the opposing team to their starting positions, effectively removing the threat of being tackled.
- The normal Yooyu has visually been replaced by the Snow Yooyu.
- The Snow Yooyu has visually turned invisible, and can now only be identified by its shadow on the field and the snow trail it leaves behind when shot.
- Some players have changed their starting positions in formations on some teams. Teylor Nix has returned to Mystery Island.
- The opponent goalie's AI has been significantly upgraded, rendering many of the usual methods of scoring no longer possible.
- Opponent teams now stick to their correct formations and no longer switch each match.
