Season 197 of a 1.19j game here: http://dl.dropbox.com/u/19969679/Elemental/119j/119j_197.EleSav
I took over the settlement of Food3 from Kraxis a few turns ago. When I went to build caravans it only allowed me to create 2, not 3. I think there must be an unassigned caravan somewhere under Kraxis control but regardless, shouldn't the caravan count reset when I took it over (i.e. allow me to create 3 and not just 2).
I just took over the settlement Aneanitel from Kraxis this round and was able to queue up 3 caravans. Based on prior experience I think this is due to an open caravan under the prior faction control - the count is counting against me, please excuse the pun. Thanks.
