Trouble with monthly recurring tasks
I mainly use the Android app, so I only noticed this weird behaviour yesterday.
There is a monthly task set to repeat on "every 15". This month I did it on time and checked it off in the Android app. The next instance was created in the app with due date on Jan 15 2014.
Yesterday I logged into web interface and saw that I had this task overdue from Dec 15. I thought that maybe it wasn't synced correctly and synced the app again. This resulted in my getting the overdue task back in the app, as if the web version was more important.
Then I tried to check the task off on the web interface. And found out that it got checked off at first, the next instance was created with due date on Jan 15 2014, but upon any further action (say, filtering tasks by date, reloading page etc.) it reverted back to being overdue from Dec 15.
I suspect that it's some web interface glitch, because everything was okay on Android. Maybe it has something to do with the next instance being set in another year? How do I get rid of this task without having to edit it?
This may be related with the bug during the summer/winter time change. We've fixed this issue already, but unfortunately, it will continue to affect tasks created or edited at the time it was present. Sorry for the inconvenience.
That said, the only way to correct this would be to either edit the task or delete it and add a new one.
