1. The The Vault quest in the Lathander Temple has to be solved before starting the dragon-quest from DSotSC. Otherwise, the priest of Bane(?) vanishes after the dragon-quest and the death knight appears in Beregost. Afterwards the priest reappears in the temple.
All in all not that problematic, but maybe not intended (?)
2. More problematic: Halfling Gandolar Glücksfuss / Luckyfoot is not in Gullykin anymore after the dragon-quest, but is actually necessary for a quest from The Vault.
A comment from Lollorian:
From the tp2's, it looks like DSotSC's Gandolar Luckyfoot () is DSHALF01.cre while Vault uses the BGT Gandolar - GANDOL.cre ... It actually looks like DSotSC creates DS-versions of all the Gullykin li'l peeps
