It's not a bug, you guys are simply missing an event somewhere.
I'll try and make it clearer for the next update. In the meantime, we've made a FAQ for commonly asked questions that will be up later.
How do I get access to the store or bar?
For the store: You'll need to meet Sarah two times. Follow Pamela's path to do this.
You'll need to progress Elsa's questline a bit up till the cafeteria.
In general, it's not possible to visit either location before day 40.
For the bar:
You have to do Sophia/Lilly's and Emily's questlines for a bit.
It opens around day 42 during the evening/night after a Sophia event when you visit Emily.
