As i've said several times: Withermoore's Soul Jar will only close properly if you go to
Braccus Rex's Tower and move towards the source barrier, Withermoore will remove the barrier and the quest will close before leaving the island.
I think Larian *should* make it so quests close regardless of what extra bonus they may provide, that should be left up as surprise anyway.
The burning pigs is done properly, that one will only close if
you cure one of the pigs that is actually a human merchant) or kill her if the water wasn't blessed
