Money repaid with no interest: does this happen a lot?

Bondora have recently introduced much stronger identity checks to comply with regulation.   This has caused many recent repayments because they have listed the applications before checking the id.   Where the id checks have not been completed they have cancelled the loans and returned the funds to investors.   This has not been ideal because their system showed cash transferred to borrowers, whereas it has been held elsewhere and there were even phantom interest payments made which were later cancelled and deducted from the repayments.   I even had one which was initially loaned in April.   At least there may be a benefit as we may have been protected from fraud and so a total loss.
