Comment 5 for bug 1195639

SirVer: they are defined. I improved the s2map.cc code during the seafaring code improvement. However it seems I have to reimprove it again :).

Fix for the bug is committed in rev. 6609 - I copy the commit message below, so I do not have to rewrite the fix explanation ;):

"Add function to determine the maximum theoretical available NodeCap of a field (without any map object on the field and neighbours) and use that function during seafaring expeditions to check whether a port space in the list of port spaces is valid - further readd a functionality to the map saver to remove all port build spaces from the port space list which will never be usable (this might break scenarios like the atlantean campaign, so we have to take care about port spaces in special scenarios manually, however this seems to be a much more smaller problem) - Fix the atlantean campaign map 1 according tothis change. This commit will unfortunally (as with the last two releases) break the savegames from atl01.wmf."
