loading das schloss xml into your tool brings up error message, possibly because several territories have no borders as they cannot be attacked but can be bombarded.
can you check this out please.
it still loads the file so i can adjust the coordinates for centering, but produces that error message.
Those are just warnings, no need to worry. I don't see any errors.
What I have been considering is improving that warning to only show up if a territory cannot attack or bombard.
Alcatraz in San Francisco would flag up a warning.
If any territory can either attack or bombard then I could remove those types of warnings for territories that can only bombard.
Currently these type of warnings are:
Warning: Territory X cannot be attacked
Warning: Territory X cannot attack
Warning: Territory X attacks Territory Y but not vice versa
The last one will flag any one way attacks just in case this is a mistake.
The first 2 could be modified to
Warning: Territory X cannot be attacked or bombarded
Warning: Territory X cannot attack or bombard
