I am very certain I didn't already collect my pets incomes today; I'm 6 hours ahead of Subeta Time and have just come home and online for the first time today. Still it says I collected the income, and I tried refreshing but just get the same error. It's not that big of a deal, I'm just confused and wondering if others have the same problem...
I just collected with all thirty five of my pets no problem. I don't see any threads on it in Problems & Bugs and it's been three hours since you posted. If it were a common problem someone would have started a topic. You should file a Ticket in Help and see what they say.
