It shouldn't be too difficult to implement the sleeping parts in the evening. They could well work as place holders in case you want to flesh out the respective actions later.
I like the idea of them running around if not present in a specific location. It would definitely improve the immersion.
And Vee could have a loading station installed in the mess hall for better socializing.
These are just random ideas to make a great game even better. In my opinion at least.
Thank you so much for your continuous additions and improvements.
