Errors Due to misconfigured vendor

The Vending machines you are using cause the following error to continously spam console every second:
 

NullReferenceException: Object reference not set to an instance of an object

I had to remove all vending machines in order to solve this. Please correct the vending machines.

Have you tried to break the prefab and then load it again?
