Hi All.
Well I hadn't realized quite how broken that last version of the game was, a lot of it was due to the changeover in animations that broke a lot of the previous ai tasks.
We have done a complete rework of the navigation system now and managed to improve it significantly, even if there is a fail on the move I have included a back up fail safe that should keep the people from freezing, Now occasionally it may result in someone doing something from a slight distance away ( as in he tries to get to a station fails and then builds that station from 2 metres away) not desirable, but much better than an ai freeze forcing people to save and reload the game.
We now have a notification for saving and loading, so if you don't see a message then it hasn't done it.
Same goes for clicking on stations, the cursor will change to a hand if it doesn't rotate the camera as sometimes you can get funny angles where it does not want to detect them.
You should now be able to do everything and have no freezing, let us now how you get on!.
