nick_h_nz: I have been without computer (and therefore internet access) for the last couple of weeks, so have only this evening seen the DNF logs. To be honest, I was expecting the cache to be muggled, as some cachers these days seem to have no idea how to rehide a cache. (It also seems some cachers these days have no idea how to retrieve a cache either, since they feel able to log the cache as found even while stating in their log that they did not attempt to retrieve it. Yeah, right, nice one....)
It lasted longer than I thought I might, given how irresponsible and selfish (or perhaps just naive and thoughtless) many newer cachers are these days. Oh well, as an experiment it succeeded, in that I expected the cache to fail, and it did. No wonder I have little faith in GC.com these days....
(PS, I have checked this cache at least once a week since it was unarchived, and almost every time I have had to rehide it, because it has not been replaced where it should have been. In its original incarnation, I also checked the cache at least once a week, and not once did I have to rehide it.)
