I don't know if anyone's mentioned this particular twist, but I think I should caution players who might try playing legacy or other challenges using the consignment shop for self-employed sales.
I started my very first Founder for a legacy and since she was an artist and gardener, she registered as a self-employed painter in Sunset Valley. Cornelia Goth was her consignment clerk and everything worked out well. Then I realized that a normal span would not be enough time for my style of playing, so I extended it to long span. My guess is that the town continued at normal span, because Cornelia retired and was replaced by a Langerak. Ever since he took the till, the shop has been bugged. I have the option to buy, but it vanishes until I remove consignments, then seems to work and let me consign new stuff. Unfortunately, my brilliant paintings don't sell anymore. I remove them and wait a day, put them back, no sales.
I could sell the work outright, but I've adapted my play to the higher sales. I clearly learned that townies live normal span, and now I understand why normal spans are the limit for legacies. I guess I'm trying to raise too many skills for the shorter life span for the founder.
I wonder if others have found that the retirement or change of clerk affects the consignment shop.
