hmm… i’m guessing by “summon trader” you mean the trading stall ones, yes? if so, i’m not sure that those traders get affected by the lvl2 town, i think it’s just the “ambient traders” that get effected…
Yes, the trading stalls aren’t effected from the town upgrade. Only the ambient ones are changing and provide for example cooked food. The implementation of the trading stalls had its foundation in the process of limiting the inventory a town can sustain. They are primarily supposed to be a place to sell items (or to buy wood as Rayya’s children)
