Hi,
I'm posting it as a bug because whatever I do, all dupes get to reach a 100% stress level even when my stress management is better than in my previous games (where I was never reaching such a level of stress)... obviously I did what you say (enclosed rooms, and isn't it written in the changeLog of the Expressive Upgrade that it's no longer needed to put some doors ?), or tried to (but as they are too stressed they won't perform the jobs I'm asking them to do).
Maybe I'm not doing it properly and it was easier in previous versions but it's such a big change in balancing that for the moment I consider it as a bug... Did you try my save file ?
I'm not the only one saying so or I'm mixing up ?
Thanks for the help.
