I am really baffled by the Spin Doctor badge (spin 2051 fibers into 293 thread in one super long spin).
The spinner just can't process so much fiber in one go, so I thought the badge description was just a fancy way to say "spin so much stuff"... but it is not, as I spun over 2300 units in batches as large as I could (repairing the spinner as it got close to breaking) and I got no badge.
So the question is: what do you actually have to do to get that badge?
