When visiting Special:Recentchanges or Special:Contributions, many rows say that it was rolled back from the previous version. The user and version are blank.
This occurs only for edits made to articles since 2.2.0. Edits made before 2.2.0 and new article rows are not affected by this. Basically, the user's IP address is saved into the wrong field for edits (the rollback field).

To remove the erroneous rollback info, run the following MySQL query (substituting {prefix} with your forum's TABLE_PREFIX):
Code:
UPDATE {prefix}vault_revision
SET rollback = 0
WHERE dateline > 1233445602
AND revision < 256
AND ipaddress = ''
