New type of Data problem should probably be added
I was doing some work merging duplicates, and I noticed that my ancestor was listed in the timeline as having been buried months before she died. There was no data problems alerting anyone to this discrepancy. My suggestion is that you should add a data problem indicating that a person was buried before they died. That way, issues like this can be fixed easier. The alert could also serve to better warn of possibly incorrect merges, since incorrectly merged people may have different burial dates. I realize that it may not be the most urgent issue to solve, but it could be a useful change nonetheless.
