Greatly appreciate the bug report. This sounds too awful to be true, however. Increasing priority. Pushing to next versions as did not make the 4.0.14 release. Needs triage.
Marked as not affecting and as fixed for 4.1.0 since testing doesn't reproduce the bug there – need to test 4.0-patches and if this doesn't appear there either, I suggest zapping it as a Can't Reproduce until it comes up again.
In the era where Respondr was being implemented, I believe there was at least one period where enabling or disabling aggregation caused personalization to break. I think it's been long-fixed, and I just tested master & 4.1.x to verify.
