[21:05:13] [modloading-worker-0/ERROR] [patchouli/]: Failed to load book rebornstorage:rs_book defined by mod rebornstorage, skipping
java.lang.IllegalArgumentException: Book rebornstorage:rs_book has use_resource_pack set to false. This behaviour was removed in 1.20. The book author should enable this flag and move all book contents clientside to /assets/, leaving the book.json in /data/. See https://vazkiimods.github.io/Patchouli/docs/upgrading/upgrade-guide-120 for details.
