After my visit here today, I can witness that this TB is not present in GC31JE2. It is obvious that this TravelBug has been lost for more than 2 months. Nobody has logged even "Discovered It" since 2015-09-27. Of course you should ask all finders of the cache at the end of September, whether somebody of them saw it or took it, but has not logged it properly on the web.
Because currently, it can be wherever, but absolutely not here, I ask you, infiniteMPG, to mark it as "missing". (One of the GC and TB cemeteries, where GC can "rest in peace" forever, is e.g. cache GC1A8K2.) Thank you in advance.
