As far as we know, this is on purpose. Ergo, according to this definition, not an exploit.
As stated abowe ... if we would use this method, then exploits (at least in this game) dont exist.

Nah, i dont read mind ... im just connecting dots ... like everyone else.

But "
nothing indicating" ?
I mean ...
Why cant we automaticky pick it from our stash, even tho this particular suggestion appears around here since patch 3 (or 4 ... not sure, anyway more than several patches allready) as i stated more or less once per month ... that means if i count corectly between 10 and 14 topics ...
And yet, there is "
nothing indicating" that Larian would like the idea ... isnt that reason enough to presume this dont work well with their design in mind? O_o
I admit without torturing ... it is to me.

Also:
- food have weight, it allways had weight and our characters can carry only certain amount of things ...
- our party of Larianpers in PFH litteraly dragged all their food with themselves in their inventories ...
- the only place from where food can be used for Long Resting is our inventory ...
Those are indications for what?
A) Food should be send to camp by some supernatural way and "by desing" used from there.
B) Players should be carrying food with themselves.
I mean, feel free to disagree ... its not like i can stop you anyway.

But i just cant help the feeling that using "mind reading" to figure this out would be like trying to kill a mole with a rocket launcher. :-/
Teoreticaly possible ... but ridiculous overkill.
