I've created a number of tasks in a list that are all scheduled and all dependancies are set up. If I move the entire list in the Gantt view, it shifts all the tasks, but they get screwed up. The duration of some changes (they span one day instead of two), the position on the timeline of some changes relative to other tasks (1 task was on the day before the next task, now they're both on the same day). Is this a known issue?
