Well, I guess that any worry about having enough food looks silly now in retrospective. I played a bit with the new patch yesterday and I noticed that I had yet to leave the druid grove (heading to the Blighted village and then goblin camp) and I found myself already carrying enough supplies for TEN full long rests. Which is like, three times more than what I did during my entire past playthrough.
I don't think anyone is going to starve at any point in this game.
Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
