Recently I encountered a case where some liquibase scripts were not executed on a mssql database.
In the databasechangelog table of the database the scripts are marked as executed, however the changes to the schema were not made.
Sadly, logs of the execution are not available because it was reported late and the logs were already auto-deleted.
one of the .xml in question is 00000008_V3.2.1.5_3592#DropCommentsColumnInQualityValue.xml
