Yeah, there is currently a bug scuttling around, where if you click the gourd buttons, then every time you harvest, it will use a gourd if you still have any (harvest is space). This bug will be fixed after the voting stage (the fix is quite simple), but for now the hotkeys (Pumpkin Pie: 1 or P, Banana Squash: 2 or B, Cucumber Cracker: 3 or C, Red Pepper: 4 or R) work without any issues.
Thanks for playing! I hope that pumpkin was delicious!
