The Overpass API cannot fetch the complete edit history for elements edited multiple times within the same second.

For instance, when an element is created and modified simultaneously, like this:

Requesting version 1 returns empty results:

One solution could be to silently ignore such issues (or workaround them by using some alternative logic), but I prefer addressing these problems at their root to ensure reliable reverts. Another approach is to await OSM-NG, which will offer an alternative method for querying element history, eliminating dependency on Overpass and significantly improving efficiency. I'll implement the second solution, but it will require some additional time. You can track the NG development progress at https://github.com/Zaczero/openstreetmap-ng.

Even giving more clear error message would help here
