When I come back to the [Matching] page from a table I had joined via a [join] button (and then left via [Leave Table]), the whole "Friend/Activity" table has a height of almost one line only. Scrolling with the mouse wheel is possible but not very comfortable. This stays that way until I refresh and login again.
Second interesting detail: Watno is shown as "Spectating[join]", Stef as "At table (spec)[join]". Actually, both are still at the league final table (both spectating).
