As for mods:
Please remember that as of now modding is not officially supported. It's done at your own risk, there are no guarantees for future compatibility. Please keep backups of your save files before you start modding. If you need technical support, please always include a full list of active AND prior mods, since that can influence the game's behaviour with regard to bugs.
