Seriously theses bugs are so bad I can't imagine how anything can be tested

Level 0 buildings appear on builds
Population never changes regardless of cottages level or number
Level stays at 2 cos game isn't recognising builds
Nearly impossible to upgrade buildings , and never sure if it is still like that when you log back in

If you are testing main code you may need to rethink and deploy premade cities so that we can offer any help,
