Hit enter too soon! Anyway, all my players are reporting that we don't seem to be getting any effects from our books. I am not sure how to help debug this, but please let me know if there's any logs or anything I can get you that might help. Thanks!

Hi, I haven't been able to reproduce this issue on dedicated servers. We have also managed to test this successfully in LAN world with 3 players, so I'm not sure what could be the issue.
Are you certain that any conditions are fullfilled (like album having atleast 300 points / or having all cards in some categories)? Also you need to have the album in your inventory (and if you have multiple albums, they will conflict with eachother).

Looks like this issue was present only on 1.18.2/1.19.2 Forge versions. I have fixed it and uploaded new version to curseforge. It should be available soon
