What actually happened was...:
Describe what happened here

The hopper would fill the brewing stand the first time, then if the bottles were removed from the stand with another hopper the first hopper would not drain thus refilling the stand

Steps to Reproduce:
1. Place a hopper feeding into the side of a brewing stand and a hopper bellow the brewing stand which will remove the bottles
2. Place water bottles into the feeding hopper which should pass through the stand and into the bottom hopper
3. Now place more water bottles in the feeding hopper, the bottles will remain stuck in the feeding hopper
