When preparing my cache-trip for today and checked for the trackables, it turned out that in fact none of them is present in the cache "Worm".
On January 16 one TB was retrieved by Banjobende (cf log).
To save your butterfly, I would recommend to politely contact every finder (since the coin/TB was placed there) by mail to get his memory jogged.
It also might be helpful to include a picture of the trackable on his page, then one knows what to look for.
Unfortunately the good habit of including the "Ins" and "Outs" in a found-log is in severe decline.
Either there's somebody in the area, using this cache for the enrichment of his collection.
Or a high percentage of cachers is hit by spontaneous amnesia at this place, regarding trackables but not the "Found".
Kind regards,
