It throws errors when I click on Lily and Cas's rooms, but can be rolled back or ignored. The game crashes when you buy gifts, and click on them while it was in the spot at the top of the screen where the inventory is. That error seems to be because it's calling non-existent labels for those items.
I also seem to have hit a wall. I can't get my points with Paige above 14, and you need 15 to progress. And with Cas, I have no idea what to do with the 'early day' hint.
How are you supposed to save money to purchase upgrades? The only time I can talk to them is at the restaurant, and their options are 'nothing' and 'how's business/work shift.'
