Observed behaviour

When entity that does not have the forge:reach_distance attribute (all non Player entities in vanilla) attacks with an ItemModularHandheld item the game crashes.

ItemModularHandheld#sweepAttack accepts any LivingEntity as attacker and always tries to retrieve the reach distance from it:

I have not reproduced this myself, but got a bug report for my mod Vampirism.
TeamLapen/Vampirism#982

Expected behaviour

Check if the attacker has the reach attribute. Otherwise use a default value.

But maybe I am missing something here, and Vampirism is at fault.

Steps to reproduce

1. Give a Vampire minion (or probably any LivingEntity without the reach attribute)
2. Let the minion attack?

The bug report was from me, and yes its JustAnGhost or "Just A Ghost, Don't Mind Us" I haven't really tried to replicate it, but I probably could if I use the same world
