Happens for id 5505. A solo #1 for NAC. Poor Timothy.
Also happens for some cases with only 2 records? See hupo-worm version 1 non-normal runtypes.
Should be fixed now.
Records are given a different "status" when they're invalidated (e.g. when releasing a new version of a map which makes the fastest times harder/impossible to beat). The compare function was only looking for records with "valid" status, and ignoring any "invalidated" records, hence the problems.
