Anyone who has not yet done so, make sure to submit a bug report and/or flag the game. If enough players respond, the issue is more likely to be dealt with, one way or another.
One problem I see is that you lose money on the higher level 8-hour harvest animals unless you harvest three times a day, which requires either exact timing or losing sleep. For these animals to be worth their purchasing cost, I would suggest that their "life left" timer be frozen when their product is ready and their food is empty. This way, they are still profitable for everyone who buys them.
