I don't seem to be able to remove the town hall. Is the "general remove building option" done by clicking on the "remove buildings" button? If I try to remove it, it says it can't be removed.
Well I just tried again with Windows and exp. and forstat is not responding and lock up!! I have to recover from it all and start over. If it is that way then it needs to be updated to work with then current Expl. and Windows. It worked with the old versions but the new one will not work at all!!The city planner works fine, I just clicked the linked and it opened with no issue. Maybe try loading it from another browser?
