lost in the wilds

I found a cache about 6 months ago where the logbook was soaking wet and didn't have accurate coordinates, it was only a few months old. I logged a Needs Maintenance (the third person to do so), but since then no maintenance has been done. 2 weeks ago I messaged the CO and offered to adopt the cache as they were doing nothing with it, had found nothing in over a year and hadn't logged on since just after they placed the cache. I have now logged a Needs Archived as they didn't respond.
