Now that you have processedBlockheight and processedConfirmedTxs in server state, stop caching the entire tx history of the alias registration address.

Delete your confirmedTxHistory table from your database
node index.js
Send 2 alias registration txs and 2 non-alias registration txs to the alias registration address
On block, database updates correctly, new serverstate is accurate to tx history
