I don't really care for Gale's personal quest, but yeah, that's a pretty big loop hole. It's a relatively easy fix though - even just by despawning his corpse and have the PC react to it quickly would be fix it.
The other one is big one that bugs me is the "die and revive" method of tadpole removal. Mainly because the game went out of its way to introduce this plot-hole in. Unless, this was all done intentionally - i.e. the main characters' tadpoles are somehow different (hence why they don't leave). But that is pure head-canon right now.
Many RPGs create a problem for themselves when they introduce an urgent, main-motivator in a world loaded with sidequests. I will give BG3 credit for doing a better-than-average job of forcing initial urgency while giving you an excuse to explore/sidequest. Most major side quests in BG3 are at least framed as potential solutions to your problem (the ruins, the druids, the goblins, the hag, etc).
Sure, the story does walk-back on the whole "urgency" thing a bit by the end of the EA, but you didn't know that until you got there, and it was enough to kickstart a whole variety of quests.
That aspect, at least, is a bit better than BG2 when there was a clear disconnect with further side questing in Ch. 2 once you've got the 20k, or in Ch. 6 since you're missing a chunk of your soul.
