It is not obvious (because you don't see it on your monitor) but I found this while roleplaying with a friend:
In the freshly introduced houses if you use any interactive chair/stool/sofa and sit on in, you see yourself in the sitting pose but the friend in your house does not (you are still standing on his screen). What completely ruins the purpose of the interactivity of chairs. Interestingly though, various fires and braziers if ignited or extinguished work properly and all see them in the correct state.
I'm playing on Windows platform, EU Server.
