Please note that the pic only shows “Samite Satchel -1” with no failed spell pages, no spell pages, no map, no Skelos armor page, and no satchels dropping after opening the pack.
I do not think this is tied only to the Samite Satchel pack but I do not currently have any pics of the other packs not giving anything upon opening them. If I get pics of other packs not dropping anything I will post them.
EDIT: The Samite Satchel pack was obtained in the Den.
It’s not just the “Samite Satchel,” this bug occurs when you try to open more than one sorcerer bag in close succession. Opening a second bag immediately after you just opened one, causes the second bag to always be empty. The work around is to wait a couple of minutes (not sure exactly how long) between opening sorcerer bags. At least that’s what I noticed in my limited testing.
It is possible (and intentional I expect) to get nothing from one of those boxes, based solely on your RNG. However, if you open them in close succession, you are nearly guaranteed to get nothing on every other box, and I expect that is unintentional.
