When I got to day 13, everyone would come and leave INSTANTLY. They would just get their order out like "Get me a polearm please." and then they would leave. I had to average out what everyone wanted and make it before they came in order to make any money. If anyone know's how to fix this, please let me know.
For whatever reason, when I got to day 13, this happened.
Hmm, when I put it on the counter and it's what they want they'll still leave quickly but quickly pop back in, get it, and pay.
Odd. Well, That was happening for me in 0.0.60. I haven't gotten that far yet in the new update, so I guess I'll see if it's still the same once I get there.
