Issue/Introduction

The Autoschedule functionality might not work on some projects.
Either Autoschedule is stuck processing until it is manually cancelled or Autoschedule almost immediately shows as completed 
(the words [Tentative Schedule] shows at the top of the Gantt page), but no changes were done to the project dates.

Those projects will also not Autoschedule in OWB (Open Workbench). 
The ‘Tracking Progress…’ window will come up, but it will stay stuck on a percentage (this project will remain stuck at 82%), and OWB will eventually stop responding.

STEPS TO REPRODUCE

1. Remove any non- working days from the Standard Calendar for the months of Dec2016-Jan2017 (leave the shifts the way they are to make up 8 hour days)
2. Create a US Calendar, using the Standard Calendar as the Base Calendar.
3. On the US Calendar, mark only 12/26/2016 and 12/27/2016 as non-workdays
4. Create 2 resources to use the US Calendar
Jane Doe
John Smith

5. Create a project with the following dates: 12/6/2016 - 1/10/2017
6.  Add the above 2 resources to the team. Jane, allocated 100%, and John allocated 50%.
7. Create the following 15 tasks: (All of the assignments are Uniform)

Summary1 (12/6/2016-12/15/2016)
--Task1.1 (12/6/2016-12/15/2016) – Fixed Duration – Assign Jane (64 ETC)
--Task1.2 (12/6/2016-12/8/2016) – Fixed Duration – Assign Jane (24 ETC) and John (12 ETC)
--Task1.3 (12/6/2016-12/7/2016) – Fixed Duration – Assign Jane (16 ETC)

Summary 2 (12/6/2016-12/19/2016)
--Task2.1 (12/6/2016-12/19/2016) – Fixed Duration – Assign Jane (80 ETC)
--Task2.2 (12/6/2016-12/8/2016) – Fixed Duration – Assign Jane (24 ETC)
--Task2.3 (12/6/2016-12/7/2016) – Fixed Duration – Assign Jane (16 ETC)
--Task2.4 (12/6/2016-12/6/2016)

-Summary2.5 (12/6/2016-12/19/2016)
----Task2.5.1 (12/6/2016-12/12/2016) – Fixed Duration – Assign Jane (40ETC) and John (20ETC)
----Task2.5.2 (12/6/2016-12/19/2016) – Fixed Duration – Assign John (40 ETC)
----Task2.5.3 (12/6/2016-12/9/2016) – Fixed Duration – Assign Jane (32ETC) and John (16ETC)
----Task2.5.4 (12/6/2016-12/6/2016) – Fixed Duration - Assign John (4 ETC)
----Task2.5.5 (12/6/2016-12/9/2016) – Fixed Duration – Assign John (16 ETC)

8. Add the following dependencies, all with 0 day lag:

Task1.1 PREDECESSOR of Task1.2
Task1.2 PREDECESSOR of Task1.3
Task2.1 PREDECESSOR of Task2.2
Task2.2 PREDECESSOR of Task2.3
Task2.4 PREDECESSOR of Task2.5.1
Task2.5.1 PREDECESSOR of Task2.5.2
Task2.5.2 PREDECESSOR of Task2.5.3
Task2.5.3 PREDECESSOR of Task2.5.4
Task2.5.4 PREDECESSOR of Task2.5.5

9. From either the Gantt or "Home > Jobs", Autoschedule the project (with options)
Autoschedule Date: 12/6/2016
Resource Constraints: Checked
Everything else is either left blank or unchecked.

Expected Results: The project is autoscheduled and the task dates change to meet the dependencies and resource constraints.

Actual Results: Either Autoschedule is stuck processing until it is manually cancelled. Or Autoschedule almost immediately shows as completed
(the words [Tentative Schedule] shows at the top of the Gantt page), but no changes were done to the project dates.
