I've noticed two issues.
1. Somehow my Food Club in-app purchase is showing to be active, although I did not purchase that. I was wondering why my food amount never went down.
2. In a house currently on the 6th generation, I've only encountered one breakdown to fix. I know they're random, but... you know

It seems an awful long time to go without, and that goal isn't ever going to be complete at this pace.
