started the offline game again after a couple of days in the demo version.
It turned out that I lost a building and the respite next to it(still able to quick travel to it), and a survivor assigned to that respite.
And the sky turned red (the one that reduces stealth effect) which I've gotten rid of by applying a card.
I lost all the things installed in and out away of that building, including crating benches and augments, etc.
