* need to scan when attempting to place, make sure no bounds overlap
with any existing civics
* needs to cache storage block locations, and only 'remove' if input

* find/fix the incorrect blocks/.png icon registration from who knows

* investigate broadcasting 'target' to vanilla/other entities (so they
will be aggro vs npcs)
    or other method to set NPC types as aggro for other Mob type
entities
