Here is a couple queries to clean up Prashnak's ID and spawn group to keep it more inline with the zoneID * 1000 standard.
Before running these, make sure to verify the npcID is 40074 and the spawngroupID is 40089. Also make sure 52087 is an available npcID and that 52077 is an available Grobb spawn group. If not, change them to whatever fits.
Code:
UPDATE npc_types SET id = '52087' WHERE id = '40074'
UPDATE spawngroup SET id = '52077', name = 'spawn23871' WHERE id = '40089'
UPDATE spawnentry SET spawngroupID = '52077', npcID = '52087' WHERE npcID = '40074'
UPDATE spawn2 SET spawngroupID = '52077' WHERE spawngroupID = '40089'
