Dense Neutron Collectors

This mod adds 3 additional tiers of neutron collectors: Dense, Denser, and Densest.

They produce neutronium nuggets, ingots, and blocks respectively

Recipes are 3x3 in a vanilla crafting table and can be reversed.

Added ability to configure neutron collection time

Warning: As of 1.1, any placed existing Avaritia collectors will be destroyed when picking them up, downgrade to 1.0b before collecting them.
