I just noticed that they've added a hangover debuff to the game. LOL
Apparently if the majority of your camp supplies are alcohol, the game now gives you a hangover debuff after a long rest. Thankfully it doesn't last very long, but that's a fun little update.
I did just use auto selection like always, and didn't pay attention to what was chosen. I'm guessing it was mostly booze and that's why it happened. You saw this when the game first came out? This is the first time I've seen it in 2.5 playthroughs.
I'm gonna run a dwarf next and pick nothing but alcohol for long rests the entire game. Enjoy the skull splitting headache, Shadowheart, you whiny elven child.
