Fixed by the json migration

Have the same problem in 1.14.4 version. Installed last version of Botania, Forge and Patchouli available in this version. Is this fix 1.15.2 version only? Any chance to back port just this fix?

1.14.4 still not fixed, 1.15.2 works fine. Probably patchouli issue

the json migration was a massive undertaking that just happened to fix that bug as a side effect. Backporting it to 1.14 isn't really feasible

Okay, so it's fixed only 1.15.2, just waiting Create port to 1.15.2.

Also this bag happens only server play, singleplayer works fine
