Expected xxx runs, but only found data for yyy

If you are getting this error with version 285 or earlier of the simulator client, wait for version 286 or later and try again! We’re working on a fix for this.

Just posted version 286 of the client, give it another try if you were seeing this issue, let us know if it is working better. If it still happens, reply here and link to the report with the error, we’ll keep troubleshooting.
