This bug report is similar to https://community.mixpanel.com/questions/1516/tracked-events-are-shown-repeated-in-the-live-view.html, except my events are not de-duplicated on mixpanel's side—they show up double-counted in the insights view as well.
The events in question are two specific events in my client-side app—the rest of the tracking events are fine. I've verified that the codepath is executed exactly one time, though, so unless I goofed somewhere non-obvious, I don't think the problem is my implementation.
The events are identical in every way except for "processing time" and "insert id"
I'm using `firstname.lastname@example.org`.
and the insights view for the current day showing that these events are double-counted against the other events, which are accurately tracked.
