Bah this is an ugly one with nested groups. You're located in a s_bookstore_2_east but even after generating new ones with the map editor several times and viewing them through clairvoyance, nothing of the sort spawns (including in the lockers). I also manually went through the item groups to find any ways this could be possible and was unable to. Just in case my manual search was not exhaustive I used the ingame item group tester to give me examples of all the item groups that spawn in that mapgen and the closest was maple syrup in the snacks groups.

Finally after exhaustively going through the item groups I found the culprit was mansion_books. Still couldn't ID the nested group so I went through and again tested the item groups inside mansion_books... exhaustively......

It stems from memorial_mansion being part of mansion_books.
