Ok, in V3 I now only have the one town listed n the right (which is the one I haven't got a family in), and have two families listed on the left, who are both in the same town (so that may be an error that shouldn't have been possible if I'd used the correct client) and say "waits for players" ("waiting for players" might be better, or "waiting for xxx players" so you've an idea of how much longer before the game will start).
...So, thought I'd join the second town as well, this then duplicated the names of those I'd got in the first town on the left, and leaves the option to join the second town again, picked another family and all duplicated again. Restart client and I have two families in each town, and no options to join a town again (which I did still have before restarting, so appears to be a check that's done on client start up that isn't done after selecting a family.
Nothing else I can now do to test more
