Down to 95 now. Apparently this is not at all uncommon, so no reason to worry.
Apparently 20ish of these people are people for whom pledges actually failed, though. We had a number of failed pledges come back in and fix up their pledge through backerkit, though, and for those other people they still can.
There are 30+ people with $72 or higher pledges, though, with no surveys in. That's the bit that really surprises me the most.
