I too have this error. I even created a test task that repeats. Without completing the task, the deadline came and went, and the task automatically skipped to the next scheduled repeat date without informing me that I had an overdue task. This is no good and will make producteev unusable for fear of missing important repeat tasks.
I can confirm this is an error. Makes repeating tasks fairly useless and dangerous as it means some tasks can be forgotten. I have had to turn them off and just manually repeat them as needed.
