Recurring tasks randomly stop repeating (Next occurrence not created)

I’ve noticed an odd pattern where some of my regularly repeating tasks suddenly stop recurring.

The Issue:

• A recurring task (set with no end date) is marked as completed, but the next incomplete instance is never generated.
• If I search for the task, I can find it sitting in my "Completed" list.
• The only way to "fix" it is to manually uncheck the task as undone, which then seems to trigger the recurrence logic again.
• This is particularly problematic for long-term tasks (e.g., yearly reminders) because I don't realize the "chain" has broken until months after the task was supposed to reappear.

Environment:

• Sync Provider: Google Tasks
• Tasks.org Version: 14.13*
• Android Version: 16*

*This problem has been occurring for years now, so not sure which version it started with

Has anyone else experienced this random ending of recurring tasks? Is there a known setting or sync conflict that causes the app to miss the creation of the next task? I waited it out, hoping it might get fixed, but since it's been years and I just found another occurrence today, I thought it was time I reach out to the community about this to see if I'm missing something easily corrected.
