As discussed in a thread with a similar title I recently asked for help on the forum.
The problem is this: I wanted to try out a new type of palace block in an older save of Valentia, but once I had set it up and placed some markets, the markets for some reason produced buyers but not traders. I checked road connection etc., but all is well. Deleted them and placed them again; nothing changed. When I later tried to place a market in an already working block, they too did not produce buyers.
Does anyone see a mistake I might have missed? Is this a bug? And if so: has anyone seen this before and is there a way to counteract it?
You'll find the block I mean on the eastern side in the middle between north and south, right next to the - currently unstable - block of large casa's.
