[1.20.1] Exception caught during Firing Event

[twohundredangels]

arrows sometimes dont hit the player,
arrows act jankily (tp forwards suddenly, bounce off entities)
all projectiles from a player appear one block below where they should fire from

we dont touch FiringEvent at all, this error is also the LivingHurtEvent. The arrows being weird isnt us, we dont touch any of that other than giving them damage attributes - do you have a custom alembicpack? this error doesnt happen with vanilla alembic by itself

[twohundredangels]

i was using a custom alembicpack; here
