Yeah, I think you'll have to run the forced updater to get the q_!armory hak updated if only the appearance.2da changed.
I really love the city reskin with all the new stuff added (i think I already had the chance to play around with an older version of this in the good, old NWNE times) and it fits perfectly with the other Q tilesets (especially when you'll combine it with the Q foliage trees from PSM's NWNE city reskin)! Graveyard terrain, the monestary and the walkable Castle roofs are still my favorites (besides the alleys for boodah-style shady dealings, of course).
But you know how I operate, so here is a list of a few things I noticed so far:
barbican - not possible to paint winkles yet
building poor - not possible to paint alley crosser yet
building burned 2x1, Group house 1 - 10 (except 5 and , arena 9x9, plaza 2x2, pool holy 2x2, all the ships, Tower Ruined, Tower Wizard, building artisan shop, building burned, building destroyed 2, plaza 1 & 2, portal, streetlight, water/dock/bridge low - still old textures
Gate, City 2x2; State Building, Ruined 2x3 - partially still old textures
monastery door, main - door missing
