The tweak

 = 1

still doesn't work as intended; a single unit isn't purchased, even though it was supposedly fixed. There's a bug when exchanging artifacts in the city building "Artifact Merchant." In the leftmost slot in the inventory, the scroll remained in place during the exchange, while another artifact (to its left) was sold – I accidentally sold the Speaker's Hat in today's game this way.
