Bug Report!
Playing version 1.66 on macOS 13.0, no mods.
On a new game, playing pretty aggressively, game refused inputs (escape for menu failed, could not click stores, but right-click for history worked) when entering the shopping center after first pet play with Brenda and buying the cat tail, but before buying the cat ears.
I was not able to reproduce from autosave.
Assume there was some event logic that I missed loading the stores.
