If you come across a bug within the game we'd very much appreciate you raising the issue for us via our community Bugs Forum which can be found here:
Within this forum there are a number of subsections to post your particular issue. If you're not sure which area it's suited to, please just create a thread in the main forum and our testing team can move it to the relevant sub-forum.
Where you can, please try and provide an example of the issue with a save game. If you can provide a save game where we can reproduce the issue ideally just before the issue occurs that is most useful in allowing us to find the issue and fix it. To learn how to upload a save game to our FTP, please read the following Guides:
