I also get this

Seems to be specifically a Folia issue

[LOOHP]

You can guess which Placeholder is failing a main thread check in the stacktrace. Seems to be a biome related one. You can either change it or make IC parse placeholders on the main thread in the config.

I'm gathering it's the %player_biome% and %player_biome_capitalized% placeholders from the Player expansion of PAPI. I don't suppose you know if I can specifically disable just those two placeholders.

[LOOHP]

You can drop their usage from the IC config. You are probably using it somewhere in there right now.

[ZepsiZola]

You're right. One of the default configs had %player_biome_capitalized%. Thank you.
