Hello, when an update has been completed by apt-dater and I select a particular host from the "Sessions" group, some unrelated tmux sessions in the same or other host-group within "Sessions" will be closed also. Most likely, the affected sessions still had a screen from needrestart telling to reboot for a kernel update. It does not seem to happen with needrestart showing just a list of programs to restart. I'm not sure if it happens with truely "finished" sessions, or sessions asking for "Ignore/Less/Connect" also. I also observe the mentioned behavior, on two different management-domains (private and company). Im using a shared setup (used by me alone, though) which worked all the way from Debian 8 until now. The mentioned behavior started with the Update auf Debian 10. So, it's not possible to check all screens one by one for messages as it was in Debian 9.
