I just logged on a few minutes before the server save to tame cu sidhe, and when I grabbed the bandages from the cu sidhe packs left behind and dropped those onto my backpack they each filled individual slots. I didn't notice that until my backpack was "full" and I had to manually drag each stack on top of the first stack. I haven't check to see if other items (gold, reagents, etc.) have this issue. Anyone else confirm? I did send in a bug report.
