One change I noticed after upgrading to 3.1 was with the Lighthouse building, there I am referring not to the Lighthouse itself but to the old Lighthouse keepers houses beside the lighthouse. I believe the houses externed much further along the lenght of the enclosed garden behind. I am sure this was not the case before 3.1. Perhaps this was intentional and I am no longer up todate .... a very long time since I lived there.
