It could be a new pattern that hasnt been verified by the moderators yet, that happened to me once. Maybe if you attach the link to the design, they will be able to tell you the reason.
at might be it! Its in the new pattern thread - I didnt know the ptterns can be posted and then approved. I thought they had to be approved first

New patterns are posted in the "new threads" area. From there they are posted to their respective forum by a moderator once the pattern is approved.

You will probably be able to access it fully in a day or so. I always go into the new patterns every day to see if there is anything interesting coming up.
