Sadly, this isn't the first time that Bimmer has disappeared like this, so it's not surprising. Last time it happened, he gave a
long sob story about how the pressure was too much, yadda yadda. Since he was making an item that people wanted (the GL ring), all was forgiven when he returned.
What is surprising is that payments were asked to be sent as a gift, when it is very clearly against the forum rules. Considering how many people were in on this run (and the Spectre ring), it's too bad that nobody reported it right away...
