Adding activity title to analysis causes the report to time out

Summary: We just activated activity sequencing so that we would be able to report on the individual modules inside a specialization. I added Activity Title and Activity Attempt Status Description to pick them up. The analysis works when run on one person, but when it's more than one person, the analysis never finishes processing and eventually times out. This happens even if it's only a couple people. Any idea why this would be happening?
