Game mechanic
Brewing interruption
A batch stops and loses its progress when the ingredient is removed or swapped, or when no bottle in the stand can be brewed with it.
Rules
| No matching bottle | The batch is cancelled as soon as none of the bottles in the stand can be brewed with the ingredient, for example when they are all taken out. |
| Ingredient changed | Removing the ingredient or replacing it with a different item cancels the batch. |
| Last-moment swap | A swap in the final game tick of the countdown does not cancel: the batch finishes with the new ingredient if it works on one of the bottles. |
| After a cancel | Progress returns to zero. The next batch starts a full 20-second countdown and spends another fuel use. |
