I also tried out the improved empathic vendor, which is really neat! However, at some point it just completely flooded my world with robot toys and rubber balls. I'm not entirely sure if this was because I was testing an older version of the vendor, or whether Creatures were able to activate that part of the vendor, but all those robot toys were rather alarming to look at. :P
