This is so weird, especially looking at books here, but I notice I have a clear tendency towards certain items. Is that on purpose? Do these items vary in "rarity"/availability? Also the patch esp. yesterday was giving me the same item twice or thrice in a row and kept repeating over the day :(

Example: I am getting the same book from a user over and over, but not the second one they are theoretically giving out. Also just these are the most expensive in Shop Search?! I've also been doing a ton of Random ToTing and thanks to mobile been ToTing kind of continuously throughout Mosotide.
