Cannot add or move workers' shifts

Today at approximately noon CDT, Schedulehead suffered from problems with adding or moving workers shifts. Workers themselves, as well as admins, were still able to login, view shifts, create time punches, pull reports, add new workers, and nearly all other Schedulehead functionality properly. The issue was resolved just after 2pm CDT. No data was lost during this interruption. Workers themselves would not have seen any problems. Thank you for your patience. For more information please contact Stellar Support from inside your Schedulehead portal.
