Using F3-H to view tags shows a block tag called "simplyseasons:junk" on a lot of items in the game (including things like paper, blank maps, and immersive engineers grit)

The tag is definitely getting applied to items that it may not be supposed to be applied to. Especially as a block tag.

This is on a custom modpack ... can send the minecraftinstance.json if you need it (custom cureseforge pack), but uploading it would be around a gigabyte of data.

Also checked logs ... no crashes or unusual mentions of either the tag or simply seasons.

If you need more info please let me know.
