This is gonna sound weird, but... I put my Tabernum up next to my Deep Mines and post to Neighbors about it and within 3 days, zit just appeared. Like when I got the Aquafier Shard, I put ponds & wells around Tabernum & got way more scales & fish than before. look in Inventory..Do you at least have the first 3 knowledge Shards? If so try moving up to mines.
