Not quick-saving enough! Shadowheart caught me biting someone before the first long rest (she must have had eagle eyes), so the whole dream sequence didn't happen - because biting someone is of course the only point of that one. In the Shadow Curse, when meeting Raphael by the Gauntlet, I did not instantly jump on the ritual specific dialogue when it casually came up mid conversation but you only have that one chance to do so, my last saving point was Last Light. And finally, the Blood of Lathander scared off Dal and Petras (and at the time I didn't realise it was Shart's mace that had scared them off) .... It was my first run, so I couldn't metagame the whole situation and it is ridiculously easy to miss these things if you are not looking for them and not hit F5 often enough. ^^
