User:Fernbom2 changed his username to User:Tostarpadius.
The log-action has been deleted, but it looks like it was made September 1 (2012).
Since then, some edits has been missing in the API-version of the edithistory.
For an exemple, edits made between "2010-06-07T20:00:16Z" and "2010-06-13T07:52:29Z":
The normal edithistory-log "Special:Contributions/Tostarpadius" looks fine as far as I can see, but they are still missing in the API-version.
I am also aware of edits missing between april 15 and april 19, 2012.
