On the questline of the Mace of Ulamak, after numerous attempts of razing/sacking skaven settlements, the tally is still zero. Went to earlier saves, restarted game and started new campaign and still had the issue.
Bug is still there with patch 2.1.1 (fr).
There is also an error with the weapon's name in the french version. It is written (Masse d') Ulumak instead of Ulamak.
