It seems there is an incorrect recipe
rubinated_nether:spelunkery/rough_ruby_block
rubinated_nether:spelunkery/rough_ruby_from_shard
rubinated_nether:spelunkery/rough_ruby_shard
rubinated_nether:spelunkery/rough_ruby_from_block
It contains invalid items

Please specify the nature of this bug report, such as posting logs. Also which versions (Neo 1.21.1 or Forge 1.20.1) it occours

I apologize for not specifying the game version. I am currently using version 1.21.1 neoforge. These recipes utilize items such as "rubinated_nether:rough_ruby" and "rubinated_nether:rough_ruby_block", but I cannot locate them in-game. Additionally, these recipes occasionally cause "kubejs" to generate errors. However, due to some modifications I made, I am unable to reproduce these errors at the moment

These were compatibility recipes to Spelunkery on the 1.20.1 version, however spelunkery is not on 1.21.1
With that said i have removed the unused files for this and immersive weathering. thank you for your report.
