We have the same issue. In two AC15 Teamwork files all of the schedules we have created have vanished
from the Project Map
. By looking at the rollbacks we know that they vanished sometime within the last 24 hours from one file. Unable to determine when they vanished from the other.
This is a real show stopper! I can only imagine the potential change orders this could create.
We can recreate the schedules by exporting XML's from the last saved PLN that still has the schedules but will lose all annotations in the annotated schedules.
I have a call into Technical Support and am waiting for a response.
