functions fail to load when starting world due to "components not bound yet"

When starting a server with datapacks present, some functions are not loaded

example

That function failed on item replace entity @n[tag=_guide] weapon.mainhand with air

But mostly it seems to be any function which has something like

give @s music_disc_creator[consumable={consume_seconds:2000000,animation:none,has_consume_particles:false},!jukebox_playable,item_name="Bucket of Pufferfish",item_model=pufferfish_bucket]

Typing reload in the console or logging in and running /reload fixes it, but as far as I can tell I’m not doing anything out of the ordinary.

It’s also being reported as

2026-01-13 19:42:18 [ERROR] Failed to load function evo:inventory_update
java.util.concurrent.CompletionException: java.lang.IllegalArgumentException: Whilst parsing command on line 4: Expected literal # at position 39: ...ntainer.* <--[HERE]

for the command execute if items entity @s container.* #evo:enchantable[!minecraft:enchantments={},!minecraft:custom_data~{tagged:true}] run function evo:update_itemswhich does look like it’s actually the components failure masked as something else.
