I have encountered this bug since last week. It happens that sometimes the repetition of the tasks run forever (past the setting I gave it initially) I don't know why this bug happens.
Also, recently, when I set the repetition and the task for one specifc day, the repeated ones appear, but not the scheduled task. e.g I set a task for 26/07 to 30/07 and the one at 26/07 doesn't appear. (This happens sometimes)
Finally I also found that if I change the date of the initial task, the repetitions are totally ignored. In the above example if I change to 25/07, the repetitions till 30 will dissapear and the functionality of repetition for that task won't work again.
Thanks in advance
