Made a larian account just to comment on this too. If the devs see this thread, I hope they know they made an INCREDIBLE game, easily my favorite RPG ever. But godsdamn did this sour the end to my first playthrough. It wouldn't have stung so much if they made it clear from the getgo theres was no fix, but her whole arc was built around fixing her up, they even foreshadowed it a couple times in different ways. Its even more baffling when you consider the game had 1 scroll of true resurrection, and divine intervention in addition to the plot hooks that were dropped in act 3.
As another commenter stated, Im also hoping she gets the Beast treatment and gets her happy ending for a new release (probably GotY edition when BG3 clean sweeps).
