Forge 40.1.52

Origin
Deathsworn

Power
Heart Stopping and Submit!

Notes
It does not matter which mobs I kill and how many, the petrified hearts don't drop.

I'm able to see the ray, but it doesn't damage any entity.

I'm unable to accumulate Soul Energy neither by killing mobs or during the night.

I don't know what causes this, but I think it is an issue with Origins (Forge)
