This TB was dropped in GC54ZEW in May 2021. The next finder of that cache was a newbie finder. All but one of the cache logs after that point were DNFs and the cache itself is now archived. I am assuming that this TB is missing, either because the newbie cacher thought it was SWAG and picked it up without logging it, or because the cache itself is now gone. Hopefully it will return to circulation sometime soon.
