I have recently changed my line up of expansion pack, they are:
When I first noticed that the consignment stall was not open I left it a while and tried again making sure that I visited early afternoon. I made several visits, however, the till never manned.
I did a restart by putting at one side the saved game, deleting the sims 3 folder and regenerated it. Replaced the saved game, but the situation had not changed.
I repeated my earlier steps and tried a new game, but the situation had not changed.
As I play from DVD installed games and had uninstalled some other expansion packs I thought that may be the problem.
I uninstalled the whole game using Revo Uninstaller and reinstalled all, the base game and the packs I wanted. Used the super patch and tried again with a new game, but the situation had not changed.
Is there some sort of clash between any of these expansions I am using? It is not a game stopper but an annoyance.
@BillFlowerpot There shouldn't be any reason that those particular packs prevent a consignment specialist from spawning. Could you start a new save in Twinbrook and see whether you get one, just to check? Please let the save run through Monday afternoon, in case it takes a day for the game to assign the sim.
If you'd rather not mess around with any of this, you could use NRaas Register to manually assign a sim to work the register. Details on how to use the mod are on the NRaas site.
