I was just informed by a customer PM that their keychain order was cancelled because of the following: Reason: Multiple Parts in a Model Description: The model is composed of several shells that are not joined together. The model cannot be printed unless the file is modified. These keychains have been printed many times and this a recent development. I have not modified the model in over a year. Looking back on my sales report, it seems another order in Dec also failed - I have the yippee email but the report does not reflect that it was completed and shipped. What's changed? Also, I never received an email about either cancellation! That's a problem as well!
