Pinned Post Disappearing? (Patreon)

So I don't know about you guys ,and I just notices that my request post for some reason isn't pinned .And even tho I tried to pin it again ,doesn't seems to be working .Either it's my connection or issue with patreon itself .So ,assuming it wasn't pinned ,you can use the search bar and search for request post / you can find the tag request post .Not sure why ,but oh well ,maybe Patreon's fault.
