Wanted to put 23 sticks into a kiln. had to pile them first and then take out 23 (custom client feature btw) and then Ctrl+Shift them into the Kiln. Except I had 3 pieces of crap-quality coal with me for some reason. They lowered the fuel quality by almost 40 points.
This is also a perennial issue with crafting in general. (And all the times that ropes on belts end up ruining Potter's Wheels - seriously, belt inventory seems to be actively prioritized, at least by a recent report by a villager who had it happen.)
