Spark

There seems to be a problem in Spark where it doesn't seem to refresh/maintain the list of people in separate rooms. For example, let's say I am in Room A and Room A has Alpha, Beta, and Gamma (me) in it. Then everyone is invited to Room B by Delta and everyone joins. After a few moments, Alpha and Beta leave Room B. When I tab back to Room A, in the list of room members I only see myself, Gamma, even though I can still see chats from Alpha and Beta occurring in that room. In Room B, I see Delta and myself like I should, but I should also see Alpha and Beta in Room A, along with myself. If I leave Room A and re-enter, then I do see everyone in the list properly. This is clearly a glitch.
