I completed the Grand Master Yoda event a long time ago, but I was left missing 25 shards and they are still missing. I initially thought it was a temporary bug, but it seems it hasn't been resolved. I would really appreciate your help with this, as the character is required to unlock Jedi Master Kenobi.
