Crusader Kings II v1.05e Patch

Also available via in-game autoupdater
Paradox Interactive has issued another hotfix for Crusader Kings II, fixing an issue with the regency events and numerous typos in the database and event files. Also, when you press the claim of a vassal ruler, he should now remain your vassal, and kKingdoms that are not previously de jure part of an empire can now also be assimilated.
A playable demo can be found here.
Update: the patch is now locally mirrored (thanks: The Patches Scrolls).
