## Dead NPCs with no reclone task (permadead without intervention)

The following should be 0. I've seen it non-zero in test, possibly from old data though.

select count(*) from items i where details->>'item_type' = 'npc' and details->>'death_data' is not null and not exists (select 1 from tasks t where t.details->>'task_type' = 'RecloneNPC' and t.details->>'task_code' = i.details->>'item_code');

Fix with something like:

INSERT INTO tasks (details)
  SELECT JSONB_BUILD_OBJECT('is_static', false, 'task_type', 'RecloneNPC', 'task_code', details->>'item_code', 'task_details', JSONB_BUILD_OBJECT('npc_code', details->>'item_code'), 'next_scheduled', now(), 'consecutive_failure_count', 0) AS details FROM items i WHERE i.details->>'item_type' = 'npc' AND i.details->>'death_data' IS NOT NULL
  AND NOT EXISTS (SELECT 1 FROM tasks t WHERE t.details->>'task_type' = 'RecloneNPC' AND t.details->>'task_code' = i.details->>'item_code');

## Corpses with no rot handler

select count(*) from items i where details->>'item_type' = 'corpse' and not exists (select 1 from tasks t where t.details->>'task_type' = 'RotCorpse' and t.details->>'task_code' = i.details->>'item_code');

This is expected to be 0 - haven't seen any instances of it deviating, so any bugs seen involving corpses probably aren't due to stale data.
