 ## Fixed
 
 - (#2007) Fixed a remaining task creation autocomplete case where a status value containing another status label could leave status fragments in the task title. Thanks to @prepare4robots for the follow-up report.
+- (#2031) Fixed quick task creation failing when natural language input created a recurring task with a scheduled time. Thanks to @rdefaccio for reporting this.
