[Madde]

As infjamc already mentioned in http://fold.it/portal/node/987609#comment-6842 the group scores of puzzles older than 284 vanished from both groups pages - for example: http://fold.it/portal/node/985857/show_scores - and puzzles pages - for example: http://fold.it/portal/node/987555 or http://fold.it/portal/node/987494

Groups scores should be restored now.
