We are currently switching to Geocaching.com's new API, this have caused some unforeseen side-effects and bugs, and we are likely to both find and implement some more during this process. We are currently maintaining a post on Facebook with known issues. We would like to suggest that you Like/Follow our page.
The queue for refreshing geocache data is unusually long. The servers are working on catching up. Meanwhile our data might not be as fresh as normal.
