Whenever a customer with pink armor and blue hair enters my shop and orders weapon + shield she does not leave. Restarted several times and all other customers works just fine.

Forgott to mention that she does not say thank you untill you have closed and reopened the shop and then you get the option to press the red cross but she does still not leave, not even sleeping gets rid of her

The problem seems to persist even when the costumer is not in pink and blue hair, but so far all of the times it has been a "female" customer

It can be fixed by saving and restarting the game
