If your farm is no longer generating cash, it could be one of these reasons:
- Tank runs out of milk
- Your maker is full
- Your storage is full
If it is one of the reasons above, you could try to clear out your storage with orders or upgrade it.
If it isn't, please try the following:
- Force-close the game.
- Power off and restart your device.
In the case none of the listed solutions work, please contact us through the support channel in-game.
