[jitsi-dev] moderators/attendees not being removed after conference ends

I've been experiencing an intermittent issue with respect to attendees/moderators not being removed from a conference after the conference ends. The steps to reproduce are the following: enter a room, log into that room as host, have another attendee join, host logs out and redirects back to welcome page (attendee is also kicked out), host goes back to same room and logs in again, there are now 2 moderators and 1 guest. It seems the previous host and guest were never removed properly.

This behaviour is not consistent and thus I cannot reproduce 100% of the time. Any ideas?
