Timesheet error (Only for one user on one task): This Web Part was unable to load

Question

Hi,
We have a weird problem with Project server 2013.
We are on the latest March CU 2015 update on MS Project and Project server.
Problem:
A resource(user) is being assigned to a task. When opening the Project with the MS Project client, you can see that the resource is effectively assigned.->OK
The real problem is when the user goes to his timesheets. He don’t see this task anymore. Other users that are assigned to the same task can see this task in the Timesheets and can open it.
When the user go back to a timesheet on a period where the task was working and visible, and he open that timesheets, he get an error: “This Web Part was unable to load”
ULS log:
[bucketHash:F0949503] There was an error while loading statusing information in the task details webpart for the specified project/assignment - Project UID: 231d4fab-e08b-44fb-8d49-04f7deff207d Assignment UID: 55e2c540-c8ae-42fa-8458-c1c6e98d98f8.
This could be caused by an out-of-date link to the task details page, specifying invalid information, or it could indicate a potential problem with the project or assignment. Exception details follow. Type: 'Microsoft.Office.Project.PWA.StatusingLib.StatusingException',

We tried already to republish the whole project with the ‘Save for Sharing’ workaround
 without success.
Someone any idea?
Since we are migrated to Project 2013, we have a lot of problems with Project Server. Too late to go back

Thanks in advance,
Johan

Hi Johan,
The assignment of this user on the given task might be corrupted. Try to remove the resource from the task, publish the project, assign the resource again and publish again the project. If it is not working, try to unpublish the task (column "publish")
and publih it again.
Hope this helps,
