When longer tasks are being moved up squeeze between calendar events, they become very buggy and annoying. The single task splits up into 2, 3 or more individual task and it becomes impossible to move them around. I can not delete individual parts of the task because it would delete all of its parts and the task itself in its entirety. I don't get why they should split into multiple and not merge back together if they do. It's really frustrating because it makes it impossible to work with changing schedules
