Error on timesheet submission "An error occurred while communicating with the server.

Question

Hello, we have many users who are encountering errors submitting timesheets following our migration to Project Server 2013 (SP1 April 2014 CU). The error is:
An error occurred while communicating with the server. Check connectivity with your administrator to determine whether further action is necessary.
This follows the specific timesheet, if I open a delegate session on my machine, I can reproduce the error. However, simply deleting and recreating the timesheet has resolved it for many users, at least until the next timesheet submission.
Has anyone seen this sort of widespread behavior and have a solution beyond deleting and recreating the given timesheet?
Thanks!

Hello Joncantrell
I just ran into issue and found a way to resolve, though it may not be the best.  I think it is a bug, but here is how I fixed it.
1) Delegating as the user
2) Deleted the timesheet
3)  Going line by line, I check each task that had a status of "Not Submitted" and "Send Progress for Select Task".
4) The error came up only for one task.
5) Open that schedule, remove resource from task, saved and published.
6) Deleted and recreated timesheet
7) Submitted timesheet and processed normally.
I hope this helps
Cheers!
