Actually, no matter what class you choose, the chore quests will always be the same. First day, 4 pails of milk, 3 books to shelve, 3 types of scrolls to copy, and beds to make. Second day, 8 pails, 3 books to shelve, 1 scroll to copy, and beds to make. The bonus lessons at the end of each day are also the same for each class, but you might wish to pick the Special Ability/Spell that is better suited to your class. Beyond the second day of chores, I can't tell you definitely, but it probably continues to be that way.

(Hope I was talking about the same quests as you.)

Started a new char, Ranger-class, and I didn't encounter the same problem. I encountered a different one. I finished the first day of chores successfully, and then finished my chores for the second day. (8 jugs of milk is really testing my patience each time I do it.) Then I go out to play with Imoen and we have a friendly bout of tag. At the building near the barracks, my char stops (I believe this stop is like the one on the first day, before hide-and-seek) and Imoen comes. She then stops and no dialogue happens. I waited about one cow refill length and I couldn't do anything at all. I'm going to have to do another second day of chores, because I wasn't prepared with a quick save. Has this been encountered before?

I reinstalled BG2 in the installation order that you suggested. After I finish the first day of chores, I play with Imoen and then learn Tracking. The next day, I looked at my special abilities twice. The first time, three SAs were in there, one of them being Tracking. The second time, I no longer have any special abilities, but my SA button isn't faded. Is this a problem with CtB or another mod?

Tracking must remain there at any time after you learned it, even if you used it once that day already.

As for other 'unexpected' abilities - that is a leftover of your CHAR initial abilities that he/she has at SoA game beginning. It's impossible to remove them all at once, so I do that in script, one by one. But sometimes not all actions are taking place (or working well). So plz take it as it is. In any case, after the next rest you probably will have them disappeared.

Well, the two other SAs were expected, and I knew where the third came from. I'll try out resting the next time I play. Thanks for the quick answer!
