My Site tasks not updating from multiple site collections and show old updated date

While working through some SharePoint 2013 farm configuration for an upcoming demo I ran across an issue where the tasks link in your mysite would not load up corretly and would throw the following error

I ran across the following article that described the issue and provided a fix. It seems that the UPA security setup in SharePoint 2013 has changed from SharePoint 2010 as adding additional accounts to the UPA was not required in 2010.

For me the issue ended up being that the account I used for the work management service application had not been added to the UPA. After doing this and running an incremental crawl the tasks were showing up from other site collections for the user.

Thanks to Hong Gyem for publishing the information on the issue and the fix
