Ngaambul: It appears that another cacher has replaced this one as a "throwdown". See this article from the help centre.
A “throwdown” is a container placed by a geocacher who cannot find the original cache.
Some geocachers place throwdowns so that they can log a find on a cache that they suspect is missing. Geocaches should never be replaced without the permission of the cache owner. This can lead to multiple containers, geocacher confusion, and disputes about whether someone is entitled to log a find or not.
Can the cacher that placed the "throwdown" rather than logging a DNF please return and remove their container and as the cache owner has not maintained their cache this will now be archived.
Cache owners are responsible for maintenance.
If you wish to replace it please submit a new cache via this link. Please be sure to include on the new submission your clear maintenance plan for the new cache.
