A couple days ago there was some weird thing where the same lobby appeared like 8 times in the custom games list; I think ever since then the custom games list no longer refreshes; the co-op game list still works fine.
If I click between "Table" and "Tiles" it will show lobbies; but if I leave it on just "Table" when I first start the client it will only show 1-2 lobbies or none at all; clicking "Tiles" it then shows the normal 12+ lobbies.
