My marketplace is in Evergreen Harbour, the lot next to the Train Station. I've been playing this lot since the Eco Pack came out, and have always had vendors spawn. Now there is none. They are the Winter Warm Up Stall and the Fall Comfort Stall. There are no other vendor stalls spawned around the 'hood when playing the Marketplace lot.
I've also noticed it happening in my Brindleton Bay Marketplace lot.
Good news. I fixed my issue:
Load the lot via Build Mode
Change the lot to Residential - this will "delete" all sub-categories, but the actual building will still be there
Save and Restart Game < this may not be needed, but I did it anyway.
Re-enter the lot and change from Residential back to Community Space - "rebuild" all sub-lots, choose Marketplace again
Send a sim to visit the lot.
Yes, both vendors showed up for their stalls.
Now off to fix all my other Marketplace lots that were having the same problem.
This did only happen since the latest patch. I had the 123 error code so I installed LittleMSSam's mod to fix that. No idea if the two bugs are related, but at least this one is fairly easy to fix within game.
