My work seems to have deliberately crippled screen and tmux such that they destroy all sessions on logout (they didn't answer when I opened a ticket about it).  i.e., when I [detach and] log out, either with ctrl-D or just close the terminal emulator on my local machine, and log back in, the tmux and screen no longer have any detached sessions.1) Is there a way around this?2) If the system is killing all background processes for logged out users I can't expect to recover an accidentally disconnected session, but is there a tool for writing details of the session to the disk?  Such as there is in emacs, for example?I don't know what details to provide yet, so please ask.
