@Perdido, sorry, I was trying to reproduce your bug, but found mine instead.
About cutscene sequence, it is different according to your list of installed mods. You have Worgas mod installed, so sequence to chores is following:
1. See the dialog of difficulty level (this one is from mod, do not mess with game settings) and choose one you like.
2. See Worgas cutscene in Asylum and second part - in cage neart to your PC's one.
3. Level up your character (required)
4. See chores
Some Big World component (I didn't identified it yet) requires to set difficulty in game settings to normal and I saw this message too. And it was fighter character. If you don't change difficulty in options, you'll not see Chores. I solved this to put BGT options difficulty level to normal - everything started working. So possible solution to your problem is following:
1. Set in Baldur's Gate options difficulty level to Normal (instead of D&D core rules or other)
2. Create character and start new game
3. Go through cutscenes and chores to Irenicus dungeon and controllable party.
4. Return difficulty level to desired and play.
I think reinstall in your case wouldn't resolve your problem.
Well, in case of Mage protagonist my advice isn't working. Problem is in BGT mod itself, in a6genspl.d used for spells selection fo mages.
